Answer:
$38.70
Explanation:
If the original price is $36 and the markup is 7.5%, you'd have to find out how much the markup is in dollars and then add it to the original price.
You can do this by multiplying 36 (the original price) by 0.075 (the percent of the markup as a decimal).
The markup is 2.7, so you'd add that to the original 36, giving you the retail price of $38.70.
