Question

Today everything at a store is on sale the store offers a 20% discount the discounted price of the hat is $18 what is the regular price (The answer is not 21.6)

The answer is 22.5 But I don’t know how to get there

Answer 1

80% = $18

(divide both sides by 80 to find 1%)

1% = 0.225

(multiply both sides by 100 to find 100%)

100% = $22.50
