A ​$270 suit is marked down by ​10%. Find the sale price.

Answer 1

You can handle this in ONE of TWO ways...

1st way...

Compute the savings (of the original price of $270) which is 10% of 270 OR 0.10(270) = $27

Then subtract the savings from the original price to give you the final price;

$270 - $27 = $243 Final Answer

OR

2nd way...

Since percentages should ALWAYS add up to 100%, if 10% is what comes off the original price (the discount) then you know that the other 90% (100 - 10 = 90) is the 'remainder' or price AFTER the discount and so the final price would be;

$270 (90%) = $270 (0.90) = $243 Final Answer

Hope this helps :)

Answer 2

270-27 = $243

10% of 270 is 27

10%= 0.10 = 1/10

1/10 of 270 = 270/10 = 27

subtract the discount from the price before the sale
