Question

Video club A charged $10 for membership and $3 for movie rental. Video Club B charges $15 for membership and $2 per movie rental. For how many movie rentals will the cost be the same at both video clubs? What is that cost?

Answer 1

Write an equation

10 + 3x = 15 +2x 
      -2x           -2x
-----------------------
10 + x (1x) = 15
-10                -10
----------------------
x = 5

cost= 25 (10 + 15)
