Question

The cost of going to the big playland park for a family is given by c = 15x + 50, where c represents the cost and x represents the number of family members. how many family members went if it cost them $125?

Answer 1

c = 15x + 50

let c be $125 since c represents the cost
15x + 50 = 125
15x = 125 - 50
15x = $75
x = 75 ÷ 15
x = 5
