Question

Suppose you have $40 and earn $7 per hour. How many hours must you work until you have $131?

Answer 1

You must work 13 hours to have a total of `$131.00`.

Explanation:

Subtract the `$40.00` from the total `$131.00`. This will give you the amount that you must earn in addition to the `$40.00` to get `$131.00`.

`$131.00-$40.00=$91.00`

You must earn an additional `$91.00` from work. Divide `$91.00` by your hourly wage. This will give the number of hours that you need to work to make the additional `$91.00`.

`"91.00"/("$7.00"/"hr")="13 hr"`
