Answer:
Carlos could play a total of 15 games
Step-by-step explanation:
In the grand opening of JoJo's arcade:
First 3 games are free
75 cents after the first 3 free games
Carlos has $9 saved from his allowance
75 cents = $0.75
Number of games Carlos could play = Total saved allowance / cost per game after 3 free games
= $9 / $0.75
= 12 games
Total number of games Carlos could play = free games + games from his allowance
= 3 + 12
= 15 games
Carlos could play a total of 15 games
