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
