Shay and nadine solve this problem in two different ways. you have $25$25 in your bank account. you make $7$7 per hour babysitting. how many hours must you babysit to have a total of $165$165 in your account?

you need 20 hours babysitting  here is how you solve that

you subtract 25 form 165 which is 140 then you divide by 7 which is 20.

your answer is 20.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
