It's suppose to be -18 so I guess no real number....
200 + 200 + 200 + 200 + 200 + 200 + 200 + 200 + 200 = 1,800
Debit cards allow you to spend money by drawing on funds you have deposited at the bank. Credit cards allow you to borrow money from the card issuer up to a certain limit to purchase items or withdraw cash. You probably have at least one credit card and one debit card in your wallet.
