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"#
