Ryobi manufactures power tools. The operations manager is currently planning the production schedule for one of their products, weed eaters, for the coming season. Four different models are under consideration: a corded model, two uncorded models, and a gas model. One of the uncorded models is sold as a combined weed eater and edger.

In planning the production schedule the manager has to consider a limited budget for production costs of $$2,500,000$ and a limited production capacity for weed eaters of $250,000$ hours. The table below contains the required production hours and the production cost for each model. It also includes the selling price for each model.
