Final answer:
The remaining balance for next month's business cell phone and internet bill, after accounting for last month's overpayment of $25, is $225.
Step-by-step explanation:
To find the remaining balance for the next month's business cell phone and internet bill, we need to take into account the overpayment from the previous month. Last month's overpayment was $25, resulting in a balance of -$25. When this overpayment is applied to the next month's bill of $250, it reduces the amount owed. Therefore, the calculation for the remaining balance would be $250 - $25, which equals $225.
Option b) $225 is the correct answer for the remaining balance for next month's bill.
