Question

Alexis just bought a brand new sweater for $45. She got it on sale at a discount of 20% off of the original price. How much did the sweater originally cost? Compose an algebraic equation and solve.

Answer 1

Since she received 20% off the original price, she paid 80% of the original price.

80% of what number equals $45?

0.80 x = 45

x = 45/0.80

x = $56.25 original price
