Answer 2

Answer: Peggy worked about 200 hours.

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:

`(\$10,000)/(\$50)=200`

Peggy worked about 200 hours.
