How do you find the original price after a discount. The sales price is 55.50 and the percent of discount is 75%.

Arte-miy333 [17]

Well first we know that 55.50 is 25% so I guess multiply it by 3 to get the full price equalling nearly 166 which is closest to 165, so that’d be my answer. Sorry if wrong.
