the cost (y) in dollars of getting into a fair and riding x rides is c(x) = 1.25x + 8. You have $25 to spend at the fair. What is the domain of this situation?

Question

it has things to do with range, direct variation and etc.

Answer 1

1.25x = 25-8 = 17

x = 17/1.25 = 68/5 = 136/10 = 13.6

domain of x is [0, 13] integers only

domain = 0, 1, 2,3,4,5,6,7,8,9,10,11,12,13
