Question 167631: Mr.La Fleur pays $130 to rent a car for one week. He also pays $5 for every 100 miles that he drives. Write an equation and draw a graph which shows the relationship between the total cost of renting the car and the number of miles that are driven.
Answer by Mathtut(3670)   (Show Source):
You can put this solution on YOUR website! so we have total cost of let say C
C=130+5(m) where m is the total number of miles divided by 100. 130 is a fixed cost that doesnt change no matter how many miles are driven.
so make a graph where y axis is the cost and the x axis m(number of miles/100)
if miles driven is say 500 then m would be 500/100..so C=130+5(5)=155
so you would plot (5,155) on the graph(perhaps every mark on the graph could equal 5)
when miles driven is 1000, m would be 1000/100=10..so C=130+5(10)=180
(10,180) as you can see for every 500 miles you drive you add $25 to the cost.
