There is an $85.00 recovery amount... For the month of March, $400.00 was charged at 25% - $85.00 = $15.00... However, rather than doing that; the following was done: $400.00 - 85 = $315.00 x .25 = $78.75 … How much was overpaid or how much is owed?
It is true that $400.00 x .25 = $100.00, BUT you did not write that. You wrote $400.00 x .25 = $100.00 - $85.00. That equation is NOT correct, do you see why? The lhs equals 100, while the rhs equals 15!The initial billing was $400.00 and 25% to be paid of that $400.00 minus the $85.00 that should be recovered to give a total of $15.00
$400.00 x .25 = $100.00 - $85.00 = $15.00
