Formulate but do not solve the following exercise as a linear programming problem.
Deluxe River Cruises operates a fleet of river vessels. The fleet has two types of vessels: A type-A vessel has 70 deluxe cabins and 150 standard cabins, whereas a type-B vessel has 80 deluxe cabins and 110 standard cabins. Under a charter agreement with Odyssey Travel Agency, Deluxe River Cruises is to provide Odyssey with a minimum of 390 deluxe and 690 standard cabins for their 15-day cruise in May. It costs $43,000 to operate a type-A vessel and $52,000 to operate a type-B vessel for that period. How many of each type vessel should be used in order to keep the operating costs to a minimum?
