A farmer has 120 acres of land and wants to plant corn and wheat. Each acre of corn requires 1.5 hours of labor, and each acre of wheat requires 2 hours. If the farmer has 200 hours of labor available, write an inequality to represent the situation and solve it. Graph the inequality.

• The inequalities are 1.5x + 2y ≤ 200 and x + y ≤ 120.

• 1.5x + 2y = 200 and x + y = 120

• 1.5x + 2y ≤ 150 and x + y ≤ 100

• 1.5x + 2y ≥ 200 and x + y ≥ 120
