Peggy worked about 200 hours.

Step-by-step explanation:

You know that the amount of money Peggy earns in 1 hour is:

$\$45\ per\ hour$

According to the exercise, the amount of money she has saved is:

$\$9,215$

Therefore, knowing this, you need to divide the amount of money she saved by the amount of money she earns in 1 hour, in order to estimate the number of hour Peggy worked.

Observe that $\$9,215$ is not is not easily divisible by $\$45$ , therefore, you can round them up to make the estimation asked:

$\$9,215\approx\$10,000$

$\$45\approx\$50$

Then:

$\frac{\$10,000}{\$50}=200$

Peggy worked about 200 hours.
