15-.75x = 13-.50x
Now just find x
15 - 3/4 x = 13 - 1/2 x
60-3x = 52-2x
8 = x
After 8 games,
Julia has 15-8*.75 = 15-6 = $9.00
Kevin has 13-8*.50 = 13-4 = $9.00
Julia and Kevin are playing games at the arcade. Julia started with $15, and the machine she is playing costs $0.75 per game. Kevin started with $13, and his machine costs $0.50 per game. After how many games will these two kids have the same amount of money remaining?
