Farmer McDonald has 150 acres of land to put into crops and 8000 dollars to spend planting and raising them. He can plant two crops, which we'll call crop A and crop B. Crop A costs $40/acre to raise and crop B costs $60/acre. He also has time costs to consider: Crop A requires 25 hours of labor per acre to raise and crop B takes 20 hours of labor. Altogether, he has 3500 hours of labor that he can spend on raising the crops. If he can expect to make $150/acre for crop A and $200/acre for crop B at market, what is the maximum revenue he can realize at harvest time?
