Answer:
Number of days = 3
Step-by-step explanation:
Let
x = number of days
Rebound game rental = 4 + 2x
Girl right game center = 1 + 3x
Equate both rental companies to find x
Rebound game rental = Girl right game center
4 + 2x = 1 + 3x
Collect like terms
4 - 1 = 3x - 2x
3 = x
x = 3 days
Number of days = 3
