I added screenshots with the complete question as well as the available choices.

Answer:
25 =
(100+15h)/(h)

which is the first option

Step-by-step explanation:
We given that:
He charges $100 as enrollment fees and $15 per hour
Given that the number of hours is h, the total cost for h hours will be:
cost = 100 + 15h ...........> I

We are also given that:
The average cost per hour is $25.
This means that:

(cost)/(hour) = $25 ............> II

Divide both sides of equation I by h:

(cost)/(hour) =
(100+15h)/(h)

Substitute with
(cost)/(hour) = 25 to get the equation used to solve for h as follows:
25 =
(100+15h)/(h)

Hope this helps :)
