The Skimmer Boat Company manufactures three kinds of molded fiberglass recreational boat a bass fishing boat, a ski boat, and a speedboat. The profit for a bass boat is $20, 500, the profit for a ski boat is $12,000, and the profit for a speedboat is $22, 300. The company believes it will sell more bass boats than the other two boats combined but no more than twice as many. The ski boat is its standard production model, and bass boats and speedboats arc modifications. The company has production capacity to manufacture 210 standard (ski-type) boats: however, a bass boat requires 1.3 limes the standard production capacity, and a speedboat requires 1.5 times the normal production capacity. In addition, a bass boat uses one high-powered engine and a speedboat uses two, and only 160 high-powered engines are available. The company wants to know how many Nuts of each type to produce to maximize profit. Formulate and solve an integer programming model for this problem.
