Your bank account balance is -$6.55. You deposit $21.75. What is your new balance? Explain how you calculated the new balance.

Answer 1

To calculate your new balance after making a deposit, you start with your current balance and add the amount of the deposit.

1. Your current balance is -$6.55 (which means you owe $6.55 to the bank).
2. You make a deposit of $21.75.

Now, you add the deposit amount to your current balance:

\[ \text{New balance} = \text{Current balance} + \text{Deposit amount} \] \[ \text{New balance} = -6.55 + 21.75 \]

When you perform the addition:

First, convert the negative balance into a positive when adding: \[ 21.75 - 6.55 = 15.20 \]

So, your new balance is \(15.20\).

Therefore, after depositing $21.75, your new balance is $15.20.
