Question

Reasoning Joanne cannot decide which of two washing machines to buy. The selling price of each is ​$495. 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 Joanne should buy the first washing machine rather than the second if the machines are the same except for the selling price.

Answer 1

To find the sale price of each washing machine, subtract the appropriate percentage discounts from the original price. The first washing machine has a sale price of $346.50, while the second washing machine has a sale price of $356.40.

Step-by-step explanation:

To find the sale price of each washing machine, we can use the following steps:

1. For the first washing machine, we can calculate the sale price by subtracting 30% of the original price from the original price. So, the sale price of the first washing machine would be $495 - (30% * $495) = $495 - $148.50 = $346.50.
2. For the second washing machine, we can calculate the sale price by first applying a 20% discount and then an additional 10% discount on the discounted price. So, the sale price of the second washing machine would be $495 - (20% * $495) = $495 - $99.00 = $396.00, and then $396 - (10% * $396) = $396 - $39.60 = $356.40.

Therefore, the sale price of the first washing machine is $346.50, and the sale price of the second washing machine is $356.40. Joanne should buy the first washing machine because it is cheaper than the second washing machine.
