Answer:
4 6/11 games
Step-by-step explanation:
Let g represent the number of games that makes non-member cost equal to member cost. Non-member cost of renting g games is 8g. Member cost is 25+2.50g. These are equal when ...
8g = 25 +2.50g
5.50g = 25
g = 25/5.50 = 50/11 = 4 6/11
The cost is the same when the number of games rented is 4 6/11.
_____
