Question

Over a three-day weekend, a rental car agency charges $65 to rent a car plus $0.30 for each mile traveled. If y represents the total cost and x represents the total number of miles traveled, which function rule describes this pattern?

Answer 1

total cost=variable cost+fixed cost
variable cost=miles traveled times cost per mile=x times 0.30 or 0.30x
fixed cost=$65

so

y=$0.30x+$65

Answer 2

I believe it would be y = $0.30x + $65
