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.

Let h be the number of hours Gabriella skied.

The total amount she paid can be represented by the equation:
35 + 15h = 95
To solve for h, first subtract 35 from both sides of the equation:
15h = 60
Then, divide both sides by 15:
h = 4
Therefore, Gabriella skied for 4 hours.

To solve this problem, let's set up an equation using the given information.

Let x represent the number of hours Gabriella skied.

The cost to rent skis is $35 and the cost per hour to ski is $15. The total cost she paid is $95.

Therefore, the equation representing the situation is:

35 + 15x = 95

To solve for x, we need to isolate it on one side of the equation.

Subtract 35 from both sides of the equation:

(35 + 15x) - 35 = 95 - 35
15x = 60

Divide both sides of the equation by 15:

(15x)/15 = 60/15
x = 4

Therefore, Gabriella skied for 4 hours.
