-Lauren Wolf purchased a dress at a 20% off sale. She paid $114 for the dress. Let p represent the price of the dress.
A) p - 0.2 = 114
B) p - 0.2p = 114
C) 0.2p - p = 114
D) p + 0.2p = 114

Question

Quizplus · Accepted Answer

Since Lauren purchased the dress at a 20% discount, she only paid 80% of the original price. Therefore, the equation representing the problem would be: p - 0.2p = 114. This simplifies to 0.8p = 114, and solving for p, we get p = 142.50, which is the original price of the dress. The equation should represent the original price (p) minus 20% of that price (0.2p) equals the price she paid ($114). So the correct equation is p - 0.2p = 114, which simplifies to 0.8p = 114.
