As manager of an aircraft parts department, you need to increase prices by 17%. Customers who buy in volume will get an 8% discount. A replacement engine mount used to cost $67. To find the new price for a high-volume customer, use the following method: 17% - 8% = 9%
$67 × 9% = $6.03
$67 + $6.03 = $73.03

You calculate the price to be $72.12. What mistake was made?
