Justin charges RM11 to mow a small lawn and RM26 to mow a large lawn. He would like to make at least RM130. Write an inequality that describes the situation. Let x = # of small lawns mowed and Let y = # of large lawns mowed

• 11x + 26y ≥ 130

• 11x + 26y > 130

• 11x + 26y ≤ 130

• 11x + 26y < 130

Aleris is sending a fancy organic fruit basket to her grandma for her birthday. Apples cost RM3 and oranges cost RM2. Aleris can spend no more than RM24 on the gift. Write an inequality that describes the situation. Let x = # of apples Let y = # of oranges
