Question

During a 20% off sale, the sale price of a bluetooth radio was $33.96. What was the regular price?

Answer 1

20% of the regular price was off.

So 80% of the regular price stayed on.

$33.96 was that 80% of the regular price.

(0.8) · (regular price)  =  $33.96

Divide both sides by (0.8).

Regular price =  ($33.96) / (0.8)

Regular price = $42.45
