The answer will the answer on the top $25=$100+$15h over h

Answer: The number of hours is 10 hours.

Step-by-step explanation:

Since we have given that

Average cost of lessons = $25

let h be the number of hours a student spends in lessons.

Since each student has fee of $100 plus $15 per hour.

So, According to question, it becomes,

[tex]25=\dfrac{100+15h}{h}\\\\25h=100+15h\\\\25h-15h=100\\\\10h=100\\\\h=\dfrac{100}{10}\\\\h=10[/tex]

Hence, the number of hours is 10 hours.
