Sarah, a restaurant manager, wants to send printed mailing promotions to residents in the neighborhood. A previous mailing was delayed due to a problem at the printer's shop. Thus, Sarah wants to reduce that risk by giving no more than 4 of the job to one printer. The total job consists of 400 copies. Sarah has obtained cost quotations from the four shops that she feels can handle the job and meet the quality specifications. Below is a summary of the information: Shop 1 2 3 4 Cost per copy $0.5 $0.4 $0.45 $0.47 Base Fee (i.e., fixed cost) $300 $350 $380 $320 a. Formulate algebraically this BIP problem to help Sarah minimize the total cost of printing the mailing copies. (14 points). b. Formulate and solve this problem on a spreadsheet and solve using Excel's Solver (Provide the corresponding "Excel Spreadsheet" and the "Answer Report"). Include "managerial statements" of the optimal decision that will yield the lowest possible cost. (i.e., describe verbally the results).
