Question

Jerry had $1,018.00 in savings. last week he spent $84.00 on a desk and $372.00 on a computer from his savings. this week at a part time job sacking groceries jerry earned $88.00 and put $44.00 of it back into savings. how much more money does jerry need to put into savings to be back to the original balance of $1,018.00?

Answer 1

$412.00

Explanation:

Opposite quantities combine to make 0.

Jerry spends $456, then puts $44 back into savings.

So, Jerry still needs to put $412 back into savings.

(84 + 372) + (−44 + (−412)) =

456 + (−456) = 0

Answer 2

Original balance $1,018.00
Desk cost -$84.00
Computer cost -$372.00
Savings from job +$44.00
Current balance = $606.00
Amount to be added to get original balance:
1018 - 606
= $412.00
