Frank needs a total of $360 to cover his expenses for the week. He earns $195 a week working at a restaurant and also walks dogs to supplement his income. Frank charges $15 per dog that he walks.

Besides his $195 weekly income he would have to walk 11 dogs at a charge of $15 each to cover his total expense of $360.

Step-by-step explanation:

$360 - $195 = $165 remaining expense to be covered.

$165 / $15 = 11 walks

Therefore he needs to do 11 dog walks at a rate of $15 plus his restaurant earnings to complete $360.
