Consider a country where there are 1¢, 5¢, 10¢, 20¢, 25¢, and 50¢ pieces. You work at the Two-Twelve Con-venience Store and must give a customer 91¢ in change. Formulate an IP that can be used to minimize the numberof coins needed to give the correct change. Use what you know about knapsack problems to solve the IP by the branch-and-bound method. (Hint: We need only solve a 90¢ problem.)
