Question 1169705: Diana and Lisa are playing games at the arcade. Diana started with $15, and the machine she is playing costs $0.75 per game. Lisa started with $13, and her machine costs $0.50 per game. After how many games will the two girls have the same amount of money remaining?

$15-$0.75x=$13-$0.50x
$2=$0.25x
x=8 games
this will be $11 each
Also can do by noting that Diana has $2 more than Lisa, and game for game, she is losing $0.25 each time.
$2/$0.25=8
