Question

Bob made $216 for 12 hours of work.

At the same rate, how many hours would he have to work to make $144?

Answer 1

First, you divide $216 by 12 hours to find the $ per hour.
216/12=18
This means you earn $18 per hour. Now, you divide $144 by 18 to find how many hours to get to $144.
The answer is 8 hours.
