Answer:
Nick has to work 8 hours
Step-by-step explanation:
Nick makes 9 works x
Julia makes 12 works 6
first find out how much Julia makes you can do that by multiplying 12 by 6 witch = 72
and we know we are trying to find how many hours Nick needs to work to equal Julia so we knew they are equal
so we have 9X=72
we just have to solve...
divide 72 by 9
leaving use with X=8
