Sue has a balance of $35 in her checking account. She writes one check for $10, and three checks for $9 each. What is her balance now?
To find Sue's balance after writing the checks, we need to subtract the total amount of the checks from her initial balance.
First, we calculate the total amount of the checks. Sue wrote one check for $10 and three checks for $9 each, so the total amount of the checks is $10 + 3 * $9 = $10 + $27 = $37.
Next, we subtract the total amount of the checks from Sue's initial balance. She had $35 in her checking account, so her new balance is $35 - $37 = -$2.
Since Sue's new balance is negative (-$2), it means she has overdrawn her account, and her balance is now in the negative.
