A student has $78 in his checking account. If the student spends $12 on lunch, which number could be combined with the amount left in the account to make zero? –90 –78 –66 –12

Given:

A student has $78 in his checking account.

The student spends $12 on lunch.

To find:

The number that could be combined with the amount left in the account to make zero.

Solution:

We have,

Amount in account = $78

Money spend on lunch = $12

Remaining amount = Amount in account - Money spend on lunch

                               = $78 - $12

                               = $66

Remaining amount is $66. So, -66 could be combined with the amount left in the account to make zero.

Therefore, the correct option is C.

the simplified form is
