Our starting value: $89.50.
Deposits means putting money in the account, so money will increase.
Withdrawal means that you are depleting the account, so money will decrease.
1. 11/4 - Deposited $17.25
So you will add $89.50 + $17.25 = $106.75
2. 11/4 = Withdrawal $35.90
So you will subtract $106.75 - $35.90 = $70.85
3. 11/7 - Deposit $10.77
So you will add $10.77 + $70.85 = $81.62
4. 11/11 - Withdrawal of $3.02
So you will now subtract $81.62- $3.02 = $78.60
$78.60 is our final balance! I hope this helps!
