Define a variable ** The original price is x.
What is the discount? ** The discount is 100% - 25% remaining = 75% discount.
How much is the original price? ** The discount is 75%, so the original price is x - .75x = .25x.
How much is the sale price? ** The sale price is $6, so $6 = .25x, which is the same as 6/.25 = x.
What was the original price? ** X = $<<24=24>>24.
