Your station charges $16.50 for a lubrication job. As a promotion you sell six coupons for lubrication jobs for $90. What percentage discount are you offering for customers who purchase the 6coupon lube book?
Discount (to the nearest tenth) = %
The answer I got was 9% & my teacher grade it wrong.

16.50 * 6 = $99.00
9/99 = 0.0909 = 9.1%
