Mr. Trenga plans to start a new business called River Explorers, which will rent canoes and kayaks

to people to travel 10 miles down the Clarion River in Cook Forest State Park. He has $45,000 to

purchase new boats. He can buy the canoes for $600 each and the kayaks for $750 each. His facility

can hold up to 65 boats. The canoes will rent for $25 a day, and the kayaks will rent for $30 a day. How

many canoes and how many kayaks should he buy to earn the most revenue? What is the maximum

revenue

A hardware store packages handyman bags of screws, bolts, nuts, and washers. Screws come in 100-lb boxes and cost $110 each, bolts come in 100-lb boxes and cost $150 each, nuts come in 80-lb boxes and cost $70 each, and washers come in 30-lb boxes and cost $20 each. The handyman package weighs at least 1 lb and must include, by weight, at least 10% screws and 25% bolts, and at most 15% nuts and 10% washers. To balance the package, the number bolts cannot exceed the number of nuts or the number of washers. A bolt weights 10 times as much as a nut and 50 times as much as a washer.

Formulate the LP model to determine the optimal mix of the package.
