If $850 is deducted each month for 12 months from your checking account to pay your mortgage, what impact will it have on your checking account balance?

If $850 is deducted each month for 12 months from your checking account to pay your mortgage, the impact on your checking account balance will be a decrease of $10,200 ($850 x 12).

To determine the impact on your checking account balance, you need to calculate the total amount deducted over the 12 months.
