Maggie has $180 in her checking account. She withdraws $12, makes a deposit of $49, and then writes a check for $59. What is the balance of her account?

$158

Step-by-step explanation:

The transaction which debits (adds) Maggie's account:

The transactions which credit (subtracts) Maggie's account:

A debit increases the amount in Maggie's checking account while a credit decreases the amount in her account.

Therefore: $180 + $49 = $229

                  $229 - ($12+$59) = $229 - $71 = $158

After all the transactions, the total amount in Maggie's checking account is equivalent to $158.
