You work for Avonalliv where you resell computers that you purchase from three vendors. You need to order at least 1100 computers. Vendor 1 charges $500 per computer plus a delivery charge of $5000. Vendor 2 charges $350 per computer plus a delivery charge of $4000. Vendor 3 charges $250 per computer plus a total delivery charge of $6000. Vendor 1 will sell Avonalliv at most 500 computers, Vendor 2, at most 900, and Vendor 3, at most 400. The minimum order for any vendor is 200 computers. In addition, because of past issues, Vendor 2 can not supply more than 50% of the computers. Determine how to minimize cost of purchasing these computers. Computers must be in whole numbers.
