(c) The invitation for bids, request for proposals, or other solicitation of any contract for a term exceeding one year, including a renewal, extension or option, shall state, in addition to the other information required by this chapter:
(5) how the award will be determined, including, if the contractor submits prices for the first fiscal year and the entire time of performance, how the prices will be compared.
