A pair of sneakers is on clearance sale for $20, which is 25% of the original price. What was the original cost?

Answer 1

20 = 1/4 the original price

$80 is the original price

20 = .25(80) = (1/4)80

when you ask the "original cost" you probably meant that to be the same as the original price

although usually they're different with cost being less than price
