Sale prices: find the original price

During a 20% OFF sale, an item is marked $52. What is the regular price?

You can find the answer by writing and solving an equation:

original price – 20% of original price  =  sale price

p – 0.20p  =  52

0.80p  =  52 Simplify

0.80p ÷ 0.80  =  52 ÷ 0.80 Divide both sides by 0.80

p  =  65


The original price was $65.

Karyl bought a dress at a 35% discount sale for $32.50. What was the original price of the dress?

You can find the answer by writing and solving an equation:

original price – 35% of original price  =  sale price

p – 0.35p  =  32.50

0.65p  =  32.50 Simplify

0.65p ÷ 0.65  =  32.50 ÷ 0.65 Divide both sides by 0.80

p  =  50


The original price of the dress was $50.
