A Farmer Is Planning His Spring Planting Based on the Following Risk Solver Platform (RSP) Sensitivity Output

A farmer is planning his spring planting. He has 20 acres on which he can plant a combination of Corn, Pumpkins and Beans. He wants to maximize his profit but there is a limited demand for each crop. Each crop also requires fertilizer and irrigation water both of which are in short supply. The following table summarizes the data for the problem.
$$\begin{array} { l | c c c c c } \text { Crap } & \begin{array} { c } \text { Profitper } \\\text { Acre ( }\end{array} & \begin{array} { c } \text { Yied per } \\\text { Acre (lb) }\end{array} & \begin{array} { c } \text { Meximum } \\\text { Denand (lb) }\end{array} & \begin{array} { c } \text { Irripation } \\\text { (acreft) }\end{array} & \begin{array} { c } \text { Fetilize } \\\text { (pounds/are) }\end{array} \\\hline \text { Carm } & 2,100 & 21,000 & 200,000 & 2 & 500 \\\text { pumplin } & 900 & 10,000 & 180,000 & 3 & 400 \\\text { Beans } & 1,050 & 3,500 & 80,000 & 1 & 300\end{array}$$ Based on the following Risk Solver Platform (RSP) sensitivity output, how much can the price of Corn drop before it is no longer profitable to plant corn?
