A mechanic charges $330 for 6 hours of labor. How much would she charge for 9 hours of labor? A. $345 B. $336 C. $495 D. $339

OpenStudy (baby_bear69):

First, divide 330 in half

OpenStudy (afrodiddle):

This one is easy, all you have to do is divide 330 by 6 to find out how much she charges per hour :)

OpenStudy (baby_bear69):

^ That's another way

OpenStudy (anonymous):

165

OpenStudy (baby_bear69):

Or divide 330 in half, which is 165, so it would cost $165 for 3 hours so 330+165= 9 hours

OpenStudy (anonymous):

55

OpenStudy (baby_bear69):

no, add them

OpenStudy (afrodiddle):

( he was answering to my way)

OpenStudy (anonymous):

I know but for the other one it is 55

OpenStudy (baby_bear69):

Ohh, okay

OpenStudy (baby_bear69):

so either add 330+165 or do 55*9

OpenStudy (afrodiddle):

Yup.

OpenStudy (anonymous):

495

OpenStudy (baby_bear69):

Yep, so C (:

OpenStudy (anonymous):

OpenStudy (afrodiddle):

OpenStudy (afrodiddle):

OpenStudy (anonymous):

give each other medals I can't give you all one

OpenStudy (anonymous):

Yep. $330 divided by 6 = $55 and $55 x 9 hours of work = $495

OpenStudy (baby_bear69):
