Inequalities in Action: Writing & Solving Real-World Scenarios

A farmer has 100 acres of land 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 the farmer has a total of 120 hours of labor available, write a system of inequalities to represent the situation.

• x + y ≤ 80, 2x + y ≤ 100

• x + 2y ≤ 100, x + y ≤ 120

• 2x + 2y ≤ 120, x + y ≤ 90

• x + y ≤ 100, 2x + y ≤ 120

A school is planning a field trip and can take a maximum of 50 students. Each bus can hold 10 students. Write an inequality to represent the number of buses needed for the trip.

• 5b >= 25

• 15b <= 50

• b < 5

• 10b >= 50
