A farming operation is considering two types of crops. Each crop requires the amounts of land, labor, fertilizer, and water tabulated below per unit of crop produced. The maximum available units of each resource are also shown Ney income in $per unit of crop produced is $60/unit and 550/unit for crops A and B, respectively. Formulate and graphically solve an LP (linear programming) model to determine the number of units of each crop to plan to maximize net income. You may use Excel or another software package to check your solution.
