After a jury trial, Alfred Finch was convicted of one count of possession with intent to distribute 5 grams or more of cocaine base (“crack cocaine”), a violation of 21 U.S.C. § 841(a)(1), (b)(l)(B)(iii). The district court 1 sentenced him to 78 months’ imprisonment followed by 5 years of supervised release. Finch appeals his conviction and sentence. We affirm.
I. BACKGROUND
On February 27, 2009, two officers of the Lexington, Nebraska Police Department responded to a report of a possible burglary at 611 East 6th Street. Vincent Steele informed the officers that he had arrived home to find a window open and a door slightly ajar, and he asked the officers to inspect the building for intruders. While checking the northwest bedroom, one of the officers noticed a mesh laundry container behind the closet door, on which lay a plastic bag. Inside the plastic bag were 105 smaller green plastic bags, each containing a white rock-like substance that the officer suspected to be illegal drugs. Tests later confirmed that the substance *1060 was crack cocaine. Also in the room, the officers observed a digital scale, .22 caliber bullets, and mail addressed to Alfred Finch. Steele denied owning the drugs, and he later testified that Finch lived in the northwest bedroom. 2
Based on the drugs seized at 611 East 6th Street, a federal grand jury returned a one-count indictment charging Finch with possession of 5 grams or more of crack cocaine with intent to distribute. Finch entered a plea of not guilty and proceeded to trial. At the close of the Government’s case-in-chief, Finch moved pursuant to Fed.R.Crim.P. 29(a) for a judgment of acquittal, which the district court denied. The jury returned a verdict of guilty, making a specific finding that Finch possessed at least 5 grams of crack cocaine. At sentencing, the district court adopted the jury’s quantity finding and sentenced Finch to 78 months’ imprisonment pursuant to 21 U.S.C. § 841(b)(l)(B)(iii) (prescribing a sentence of 5 to 20 years’ imprisonment for violations of § 841(a) involving 5 or more grams of crack cocaine). On appeal, Finch (1) attacks the sufficiency of the evidence supporting the jury’s verdict that he possessed crack cocaine with intent to distribute, (2) challenges the admissibility of certain expert testimony, and (3) contends that he is entitled to resentencing under a retroactive application of the Fair Sentencing Act of 2010,- Pub.L. 111-220, 124 Stat. 2372 (Aug. 3, 2010).
II. DISCUSSION
Finch first challenges the sufficiency
of the
evidence underlying his conviction. “Where a party challenges the evidence underlying his conviction, the standard of review is very strict, and the jury’s verdict is not to be lightly overturned.”
United States v. Hayes,
“The offense of possession with intent to distribute consists of two elements: knowing possession of crack cocaine and the intent to distribute it.”
United States v. McClellon,
We find that there is sufficient evidence of Finch’s dominion over the northwest bedroom to support the jury’s conclusion that he knowingly possessed the crack cocaine. Steele testified that he rented the house at 611 East 6th Street, that he allowed Finch to move into the house in early February 2009, and that Finch slept in the northwest bedroom.
See United States v. Kent,
With respect to the intent to distribute element, “[cjircumstantial evidence such as drug quantity, packaging material, and the presence of cash may be used to establish intent to distribute.”

United States v. Barrow,
Finch next argues that the district court erred when it admitted expert testimony regarding the quantity of crack cocaine consumed during laboratory testing. The Government called Vickie Cowan, a forensic chemist for the Nebraska State Patrol Crime Lab, to testify about the identity and quantity of the substance in the 105 small plastic bags. Before testing the material, she initially weighed the contents of each plastic bag individually and added the 105 separate results together to calculate a total weight of 6.68 grams. Co-wan then conducted a number of tests on samples taken from the contents of each of the 105 bags, which confirmed that the substance in each was crack cocaine. The tests destroyed the samples.
The scale used by Cowan had a 0.03-gram margin of error. One week prior to trial, the Government requested that Co-wan reweigh the remaining material in order to foreclose any argument by the defense that the cumulative margin of error in the initial weighings supplied reasonable doubt as to whether the total quantity of crack cocaine was at least 5 grams. 3 This time, however, Cowan emp *1062 tied the contents of the 105 bags and weighed the entire amount of remaining crack cocaine in a single weighing, which resulted in a weight of 4.28 grams. Factoring in the single iteration of the scale’s margin of error, the substance’s total weight theoretically could have ranged anywhere from 4.25 grams to 4.31 grams (4.28 plus or minus 0.03).
Because Cowan’s final weighing resulted in a weight of less than 5 grams, the Government endeavored to elicit her opinion that the earlier testing conducted on samples from each of the 105 bags had consumed at least a total of 0.76 grams of crack cocaine. In this way, the Government hoped to solidify its case that Finch had possessed at least 5 grams (because 0.76 grams plus a theoretical minimum weight of 4.25 grams would yield an original amount of more than 5 grams). 4 Finch objected to the admission of Cowan’s opinion, arguing that her estimate regarding the amount of crack cocaine consumed during testing was factually unsupported and thus inadmissible. After a hearing conducted outside the presence of the jury, the district court determined that Cowan’s opinion was sufficiently reliable and admitted the evidence.
Finch contends that this expert opinion was fundamentally unsupported by any factual basis and should have been excluded under Fed.R.Evid. 702.

“We review the district court’s decision to admit expert testimony for abuse of discretion, according it substantial deference.”
United States v. Bailey,
Finch argues that Cowan’s estimate that the testing process consumed at least 0.76 grams of crack cocaine was “mere conjecture.” We disagree. Cowan initially testified that, in the course of her career, she had tested thousands of samples of sub *1063 stances, including several hundred samples of crack cocaine. Additionally, she later confirmed that her experience in analyzing and weighing small quantities of powdery substances gave her “a better judgment about the quantities involved ... than a layperson.” Cowan then testified that the contents of each of the 105 bags weighed between 0.04 grams and 0.11 grams. Based on her experience in weighing these small quantities of powdery substances and extracting portions of them for testing, Cowan explained that it was common to consume one quarter of “a small sample like the 0.04 [sample].” Because one quarter of 0.04 grams — the smallest sample — is 0.01 grams, Cowan could estimate that, at a bare minimum, she had consumed 1.05 grams of crack cocaine during testing (0.01 grams multiplied by 105 bags), well in excess of the 0.76-gram “threshold.” We conclude that Cowan’s expert testimony was not “fundamentally unsupported” and that its admission did not constitute an abuse of discretion.
Finally, Finch argues that he is entitled to resentencing under a retroactive application of the Fair Sentencing Act of 2010, Pub.L. 111-220, 124 Stat. 2372 (Aug. 3, 2010). We reject this argument as foreclosed by our decision in
United States v. Brewer,
III. CONCLUSION
For the foregoing reasons, we affirm the judgment of the district court.
Notes
. The Honorable Richard G. Kopf, United States District Judge for the District of Nebraska.
. Steele slept in a bedroom across the hall from the bedroom in which the drugs were found.
. Each of the 105 initial measurements was subject to a 0.03-gram margin of error. *1062 Therefore, according to the parties, the substance theoretically could have weighed as little as 3.53 grams (if the scale read 0.03 grams high every time) or as much as 9.83 grams (if the scale read 0.03 grams low every time). Although we question the statistical likelihood that the original 6.68-gram weight could actually weigh less than 5 grams based solely on the scale's 0.03-gram margin of error, the parties did not explore this question, and we need not address it.
. We note that, because the sentencing range prescribed in 21 U.S.C. § 841(b)(l)(B)(iii) applies to offenses involving at least 5 grams of crack cocaine, the Government need only have elicited Cowan’s testimony that she consumed 0.75 grams, not 0.76 grams.
. Fed.R.Evid. 702 provides:
If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise, if (1) the testimony is based upon sufficient facts or data, (2) the testimony is the product of reliable principles and methods, and (3) the witness has applied the principles and methods reliably to the facts of the case.
