Question

Kareem cannot decide which of two washing machines to buy. The selling price of each is ​$550. The first is marked down by ​30%. The second is marked down by 20​% with an additional ​10% 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 1

Answer: Because the first washing machine is cheaper

Explanation:

Find the first washing machine price by taking 550 times 0.7 = $385

The second machine is first down by 20%, so take 550 times 0.8 =$440

Then 10% off, so take 440 times 0.9 = $396

So the first washing machine is cheaper than the second one $11
