Question

George, the mechanic, charges $35 to change the oil on a car. It usually takes 1 hour to complete. He charges $20 for each additional hour after the first hour. How much will he earn on a car that requires 5 hours to complete?
A$555
B$115
C$100
D$60

Answer 1

Since he is working 5 hours on the car and charges 20 per hour what do you think you would do to find that part of this problem?

Answer 2

omg i know this
20 divided 5

Answer 3

Not quite

Answer 4

hmm

Answer 5

it is b

Answer 6

Hes actually working 4 hours extra on this car, so it would be 4 multiplied by 20 because its 20 dollars per extra hour. Then you would add the original price of $35 dollars to your answer, what would you get?

Answer 7

idk

Answer 8

@tarnett1 do not give direct answers

Answer 9

Well 4 multiplied by 20 would be 80, plus the initial $35 would give you $115

Answer 17

its an additional 20 dollars for every extra hour. it requires 5 hours to change the oil. your going to add 35 dollars plus the 80 dollars extra for the additional 4 hours. so once you add them together you get 115 dollars as the answer
so the answer is b.

Answer 18

Comment: Tarnett's answer is good, but would be better if re-written as follows:
"It's an additional $20 for every hour AFTER THE FIRST HOUR. Thus, the toal bill is $35 plus ($20/hour) times (4 hours).
