Marco's mom has sent him to the store to buy apples and oranges. She has given Marco instructions to buy 4 pounds of apples and as many
pounds of oranges as possible. He also has to spend exactly $9.11. If one
pound of apples costs $1.29 and one pound of oranges costs $0.79, how
many pounds of oranges will Marco be able to buy? Use the equation
1.29(4) + 0.79X = 9.11 to help you solve the problem.
