Question

membership to a music club cost $130. members pay $5 for music lesson and non-members pay $15 for music lesson. how many music lessons would have to be taken for the cost to be the same for members and non-members

Answer 1

if you add the price of a music class ($130 + 5 =$135) and then divide by 15
135 / 15 = 9
So someone that is a non member would have to take 9 classes for it to cost as much as a member taking 1 class
