Final answer:
Stephanie initially had $325.48 in her account, after writing a check for $107.85 and making a deposit of $78.88, her current checking account balance is $296.51.
Step-by-step explanation:
To determine Stephanie's checking account balance after writing a check and making a deposit, we need to subtract the check amount from the initial balance and then add the deposit amount.
Stephanie's initial balance was $325.48. She wrote a check for $107.85, leaving her with $325.48 - $107.85 = $217.63. After making a deposit of $78.88, Stephanie's new balance is $217.63 + $78.88 = $296.51.
