Suppose GameStop charges nonmembers $8 to rent each game. A store membership costs $25 and members pay only $2.50 to rent each g
Helga [31]

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.

_____

There is no integer number of games that can be rented to make the costs be the same.
