Molly's favorite store is running a great deal. All products are marked down 20% from their original
price. Molly also has a coupon with her that is good for an additional 20% off of the sale price of an
item.
Which expression shows the final price she will pay for an item with her coupon, where p is the
original price of the item?

Answer:

  • D. 0.8p(1p-0.2p)

Step-by-step explanation:

If p is the original price, the markdown price is:

  • p - 20% =
  • p - p(20/100) =
  • p - 0.2p =
  • 0.8p

Now, another 20% off:

  • 0.8p - 20% =
  • 0.8p - 0.8p(20/100) =
  • 0.8(p - 0.2p) =
  • 0.64p

Answer choices:

  • A. 0.2(1p-0.2p)
  • B. 0.6p
  • C. (1p-0.2p)-0.2p
  • D. 0.8p(1p-0.2p)

Correct one is D
