Gabriella went skiing. she paid $35 to rent skis and $15 an hour to ski. if she paid a total of $95, how many hours did she ski? write an equation to represent the situation and solve it.

Total paid = 95

rent skis = 35

per hour = 15

1st step subtract the ski rental from total price to get how much she paid for hours of skiing:

95 - 35 = 60

now divide that by 15 per hour to find hours:

60 / 15 =  4 hours

equation: 95 = 15x +35
