A farmer has 100 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 240 hours of labor available, set up the inequalities and graph the solution.

• The inequalities are x + y <= 100 and 2x + 3y <= 240.

• x + y <= 50 and 2x + 3y <= 120

• x + y >= 100 and 2x + 3y >= 240

• x + y = 100 and 2x + 3y = 240

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 the inequality and graph it to find the maximum number of classes they can attend.

A restaurant has a special offer where a meal costs $15 and a drink costs $3. If a customer wants to spend no more than $60, write the inequality and graph it to find the maximum number of meals and drinks they can order.

• The maximum number of meals is 5 and drinks is 10.

• The maximum number of meals is 3 and drinks is 15.

• The maximum number of meals is 2 and drinks is 25.

• The maximum number of meals is 4 (x=4, y=0) and the maximum number of drinks is 20 (x=0, y=20).

A student is saving money for a new laptop that costs $800. If they save $50 a week, how many weeks will it take to save enough? Write the inequality and graph it to show the solution.
