Marcel and Floyd are playing games at an arcade. Marcel has $8.25 and is only playing $0.25 games. Floyd has $9.75 and is only playing $0.75 games. Jorge wants to find the number of games after which Marcel and Floyd will have the same amount of money remaining. Jorge's work is shown below. Let x = the number of games played. Jorge knows his answer is incorrect because it does not make sense to have a negative number of games. What is Jorge's error?
