Question

jen saved $24 in june, $28 in july and $45 in august tjen she spent $72 on a camera how much money does she have left?

Answer 1

$24 + $28 + $45 = $97
$97 - $72 = $25

The answer is $25.

All of the money she saves gets added together because she is getting MORE money. When she spends money, she LOSES money, so you subtract it.

Answer 2

24+28+45=77-72=? Once you've solved that equation you should be good :)
