Mr. Cruz is the director of an after-school program. He says that 170 students, or 85% of the
students in his program, went on to attend college. A parent wants to know the total number
of students in the program.

Our total in this equation is $127.50. Let's assume there are 30 days in this specific month. If she watched 2.5 hours per day, then we'll take the 2.5 hours per day, and multiply it by the days per month (30), which will equal 75.

2.5 hours per day (x) 30 days per month = 75 hours per month

Now if she pays $127.50 per month, and she watches 75 hours per month, then divide 127.50 by 75.

$127.50 per month / 75 hours watched per month = $1.70 per hour

Hope this helped!
