Marcus rented a movie for $4 and some video games for $6 each. He paid $22. How many games did he rent? Choose two answers: one for the equation that models this situation and one for the correct answer.

A. Equation: 6 + 4x = 22

B. Answer: 3 video games

C. Answer: 4 video games

D. Equation: 4 + 6x = 22

Your equation should be:

4 + 6x = 22

This is so because he only bought one movie, but he bought "some" video games. The variable x represents some in the problem.

Solve the equation.

4 + 6x = 22

Subtract 4 from both sides of the equation.

6x = 18

Divide both sides by 6.

x = 3

Marcus rented 3 video games.

Solution:

D. 4 + 6x = 22

B. 3 video games
