Question

Bob made $216 for 12 hours of work.

Answer 1

Answer:

8 hours

Step-by-step explanation:

$216 → 12 hours

$1 → $\frac{12}{216}$ hours

$144 → ( $\frac{12}{216}$ *144) → 8 hours

Answer 2

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.
