Answer:
$80
Step-by-step explanation:
After the price has been marked up by 15 percent, the total percentage 92 dollars is worth based on the original price (not marked up) is 115 percent (100% +15%).
Hence, to find the original price (old price) of 100 percent, you divide 92 dollars by 115 units and multiply 100 to the final value to get 100 percent, assuming 1 unit price = 1 percent.
