Formulate an optimization problem that would compute the solution. No need to actually give the solution.

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 profit?
