Question

Lori had $126.89 in her bank account. She deposited $21.49 into it and then wrote a check for her car repairs for $156.61. What was the ending balance in her account?

Answer 1

when you deposit into a bank account, the balance goes up
when you write a check, the balance gets decreased by the amount of the check

with that in mind, take her original bank balance, add the deposit, and subtract the amt. of the check, to get the final balance
