A publishing house is selling subscriptions to its magazines for 20% off the original price. If a subscription to Newsweek Magazine is on sale for $72, how much does it usually cost?

90

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

let a represent price of the magazine before the discount

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
