A farmer has 120 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 180 hours of labor available, write an inequality to represent the number of acres of corn (c) and wheat (w) he can plant. What are the possible combinations of corn and wheat he can plant?

• c + w ≤ 120 and 2c + w = 180

• c + w ≥ 120 and 2c + w ≥ 180

• c + w ≤ 120 and 2c + w ≤ 180

• c + w ≤ 100 and 2c + w ≤ 150

A gym charges a monthly fee of $30 plus $5 for each class attended. If a member wants to spend no more than $100 in a month, write an inequality to represent the number of classes (c) they can attend. How many classes can they attend at most?
