Dylans mother tells Dylan he must spend less time playing electronic games. On the weekends he spends 9.5 hours playing electronic games. If he plays between 13 and 19 hours each week, how many hours does he play games on weekdays?

Let x equal the number of hours Dylan plays electronic games per week.

Set up our inequality:
13 <= x <= 19

To see how much he plays during weekdays, subtract off the weekend time
13 - 9.5 <= x <= 19 - 9.5
3.5 <= x <= 9.5
