Question

17. Bob and his friends decide to go bowling. The cost for the group is $10 for shoe rentals plus $4.00 per game. The model for this is c= 4g + 10. A. Find the inverse function. B. Using the inverse function, find out how many games can be played if the group has $114 to spend.

Answer 1

c = 4g + 10

g = 4c + 10
-10 -10
g - 10 = 4c
g - 10/4 = c <----------------------- inverse function

114 = 4g + 10
-10 -10
104 = 4g
g = 26
26 games can be played
