Graphing Inequalities: Finding Feasible Regions in Context

A farmer has 100 acres of land. He wants to plant corn and wheat. Each acre of corn requires 2 hours of labor, and each acre of wheat requires 1 hour of labor. If he has a total of 120 hours of labor available, graph the inequalities and identify the feasible region for planting corn (C) and wheat (W).
