A farmer has 100 acres of land on which she plans to grow wheat and corn. Each acre of wheat requires 4 hours of labor and $20 of capital, and each acre of corn requires 16 hours of labor and $40 of capital. The farmer has at most 800 hours of labor and $2400 of capital available. If the profit from an acre of wheat is 80 , and from an acre of corn is 100 , how many acres of each crop should she plant to maximize her profit? Formulate a linear program that solves this problem
