During a sale, a store offered a 10% discount on a stereo system that originally sold for $810. After the sale, the discounted price of the stereo system was marked up by 10%. What was the price of the stereo system after the markup? Round to the nearest cent.

"Viewer discretion advised

$801.9

Step-by-step explanation:

10% of 810 is 81

810-81 = 729

10% of 729 is 72.9, so add that back to get the extra 10%

729+72.9 = 801.9
