John checked his bank account and noticed that he had a balance of −$12.00. He immediately deposited $12.00 in his account.

What is the balance of his account after the $12.00 deposit?

The balance of his account after the $12.00 deposit is $0.00.

0.00

That is correct. The balance of his account after the $12.00 deposit is indeed $0.00.

The balance of John's account after the $12.00 deposit can be calculated by adding the deposit amount to the initial balance.

Initial balance: -$12.00
Deposit amount: $12.00

The calculation would be:

-12.00 + 12.00 = $0.00

Therefore, after the $12.00 deposit, the balance of John's account is $0.00.
