Answer:
$299
Explanation:
Make a proportion
He makes $184 for 8 hours of work, and $x for 13 hours of work
184/8=x/13
To solve, we need to get x by itself. To do this, multiply both sides by 13. We multiply because x is being divide by 13, and we want to do the opposite.
13(184/8)=(x/13)13
The 13s on the right will cancel, leaving us with
13(23)=x
299=x
So, he will earn $299 for 13 hours of work.
