Question

A radio is being discounted 20%. If the sale price of the radio is $17.76, what was the original price of the radio?

Answer 1

around $21.32, because the original answer would be 21.312

Answer 2

A discount of 20% means the price is going to be 100% - 20% of the original price, so it'll be 80%.

x * 0.80 = $17.76

x = $22.20
