Kareem cannot decide which of two washing machines to buy. The selling price of each is ​$360. The first is marked down by 30​%. The second is marked down by 10​% with an additional 20​% off. Find the sale price of each washing machine. Use pencil and paper. Explain why Kareem should buy the first washing machine rather than the second if the machines are the same except for the selling price.

Answer:

For the first washing machine, the sale price is:

Sale price = Original price - Discount

Sale price = $360 - 0.30($360)

Sale price = $360 - $108

Sale price = $252

For the second washing machine, the discount is calculated in two steps. First, the price is discounted by 10%:

Discounted price = Original price - Discount

Discounted price = $360 - 0.10($360)

Discounted price = $360 - $36

Discounted price = $324

Then, the discounted price is further discounted by 20%:

Sale price = Discounted price - Additional discount

Sale price = $324 - 0.20($324)

Sale price = $324 - $64.80

Sale price = $259.20

Therefore, the sale price of the first washing machine is $252 and the sale price of the second washing machine is $259.20.

Kareem should buy the first washing machine because it is cheaper. Even though the second washing machine has an additional discount, the first washing machine is already discounted by 30%, which makes it a better deal.
