5. (12 points) Farmer Brown grows corn and wheat on his 100 acres of land. His yield of corn is expected to be 300 tons/acre for each of the next three growing seasons (For example, if he plants 5 acres of corn, he will produce 1500 tons of corn). His yield of wheat is expected to be 110 tons/acre for each of the next three growing seasons. At the end of each of the next three growing seasons, he must meet crop demands, which are shown in the table below. The cost of planting corn and wheat increases each growing season, and these costs are also given in the table below. Farmer Brown can hold corn and wheat from one growing season to the next by renting space in his neighbor Cowboy Miller's backyard for a cost of $1/ton per season for corn and $1.50/ton per season for wheat. Farmer Brown has an initial store of 10000 tons of corn and 5000 tons of wheat that are already stored in Cowboy Miller's backyard. Write a linear programming instance that will minimize Farmer Brown's cost of meeting his crop demands over the next three seasons. Be sure to clearly define all decision variables and explain the objective and constraints of your model. (Don't solve it in Excel or Python!)
