Step-by-step explanation:
The magazines are sold at a discount. Discount reduces the price of the good
If the magazines are sold at 20%, the magazine's price would be 80% (100% - 20%) of the original price

This equation represents price of the magazine after the discount
0.8 x a = $72
Divide both sides by 0.8 and find a
a = $90
