jasenka [17]

The regular price is $22.5 if everything in a store is 20% off, and the discounted price of an item is $18.00

If everything in a store is 20% off, and the discounted price of an item is $18.00

Let's suppose the regular price is x

(100-20)% of x = 18

x = $22.5

Thus, the regular price is $22.5 if everything in a store is 20% off, and the discounted price of an item is $18.00
