Need help with two word problems

E. 18 children are buying their lunches

F. Rock must pay $50 each month

Step-by-step explanation:

E.

To find a percentage you multiply the number by the percentage;

60 x 70%(0.70) = 42 children brought their lunches

But we need the amount buying their lunches so we would subtract 60 by 42;

60 - 42 = 18 buying their lunches

F.

Again, to find the percentage we multiply it by the original;

$800 x $25(0.25) = $200 Rock paid for the down payment on the sofa

Now we need to find how much Rock still needs to pay for the sofa;

$800 - $200 = $600 more needed to pay for the sofa

Lastly, we must find how much Rock will need to pay each month to pay the rest of the $600. There are 12 months in a year, so we divide that by the amount left;

$600 / 12 = $50 needs to be paid each month for a year
