Write an equation to represent the problem

Question

Lauren Wolf purchased a dress at a 25% off sale. She paid $97 for the dress. Let p represent the price of the dress. 

Answer 1

the formula to solve this problem is Final price = original price - (original price x discount)

let Po = the original price of the dress

then, our equation becomes $97 = Po - 0.25Po

which becomes $97 = 0.75Po

solving, Po = $129.33

 

Proof: $129.33 x 0.25 = $32.33; $129.33 - 32.33 = $97
