Mr. Keene has a choice between two cable
companies. He can pay $89 per month plus $5 for each
movie rental or he can pay $119 per month plus $2 for
each movie rental. Which equation shows the number of
movies Mr. Keene would need to rent for both options to
cost the same?

5x + 119 = 2x + 89

119x + 2 = 89x + 5

0.02x + 119 = 0.05x + 89

2x + 119 = 5x + 89
