A farmer has 120 acres of land and wants to plant corn and wheat. Each acre of corn requires 2 hours of labor, and each acre of wheat requires 3 hours. If the farmer has a maximum of 240 hours of labor available, write and solve the inequality for the number of acres of corn (c) and wheat (w) he can plant. Graph the solution set.

• c + w ≤ 120 and 2c + 4w ≤ 240

• c + w ≤ 150 and 2c + 3w ≤ 300

• c + w ≤ 120 and 2c + 3w ≤ 240

• c + w ≤ 100 and 2c + 2w ≤ 240

A concert hall has a seating capacity of 300. If tickets are sold for $15 each, and the total revenue must be at least $2000, write and solve the inequality for the number of tickets (t) that must be sold. Graph the solution set.

• t >= 134 and t <= 300

• t < 134

• t = 150

• t > 300
