 Question 593978: A small farm has 70 acres of space to plant. The farmer wants to grow corn and green beans. It costs \$60 per acre to grow the corn and \$30 per acre to grow the green beans. The farmer has \$1800 to use for planting the vegetables. It takes the farmer 3 days to plant each acre of corn and 4 days to plant each acre of green beans. There are 120 days available to plant the vegetables. When the farmer sells the vegetables, he can expect to make a profit of \$180 per acre for the corn and \$100 per acre for the green beans. How many acres should the farmer allow for each vegetable in order to maximize profit? What are the equations I should use to solve this problem?
