Answer:
5 rentals for $30
Step-by-step explanation: *using y = mx + b*
Info Given:
Video Club A-
$10 (would be your b)
$4 (would be your x)
Video Club B-
$15 (would be your b)
$3 (would be your x)
HOW TO SOLVE:
Video Club A - y = 4x + 10
Video Club B - y = 3x + 15
Set them equal to eachother to solve for x!
4x + 10 = 3x + 15
- 10 - 10
4x = 3x + 5
-3x -3x
x = 5 rentals
Plug in the x into both or just one equation to find the price!
y = 4x + 10
= 4(5) + 10
= 20 + 10
y = $30
