Given:
Start - 250
Withdrawal - 56.5
Deposit - 25
Since we need to figure out their final balance, we can calculate this by subtracting their initial amount by the amount withdrawn and then adding it by the amount deposited (since withdrew means to take away money and deposit is to add money).
250 - 56.5 = 193.5
193.5 + 25 = 218.5
Their new balance would be $218.50
