Final answer:
Sofia should write $192.67 on the deposit slip after totaling her checks and subtracting the cash back amount she wants to receive.
Step-by-step explanation:
To determine what Sofia should write on the deposit slip when she is depositing checks of $123.47, $39.72, and $94.48 into her checking account and wants to get $65.00 cash back, we need to first calculate the total amount of the checks. Then, subtract the cash back amount from the total deposit to find out how much will actually be deposited into her account.
The total amount of the checks is $123.47 + $39.72 + $94.48 = $257.67. If Sofia wants $65.00 cash back, the calculation will be $257.67 (total checks) - $65.00 (cash back) = $192.67. Therefore, Sofia should write $192.67 on the line of the deposit slip.
