Question

Oscar has purchased a pair of shoes that originally sold for \[ $ 60\] . How much did he save if the shoes were marked 30% off ?

Answer 1

Hint: Star the solution by writing the value percentage in fraction form. After this part all you have to do is find the value of 30% of the original price of the shoes i.e. \[$ 60\]. From this step you will get the exact value or money that will be deducted from the original price of the shoes.

Complete step by step solution:
We have already been given the amount of sales on the shoes that Oscar bought. We have to find the amount of money Oscar saved.
30% usually mean $ \dfrac{{30}}{{100}} $
We have to find the value of 30% on the original price of the shoes i.e. $ 60 $
Therefore we get $ \dfrac{{30}}{{100}} \times \ 60 $
 $
   = \dfrac{{\ $ 180}}{{100}} \\
   = \ 18 \;
  $
Hence Oscar saved \[ $ 18\] on the shoes that he bought on sale for 30%.
Hence the total amount Oscar paid for the shoes was $ 60-18 $ = \[ $ 42\] respectively.
So, the correct answer is “ \[ $ 42\] ”.

Note: Similar to this sum there are many types of other sums which ask you to find the final value of the goods bought after applying the sale to the product. All you have to do is subtract the amount of the sale from the original price and there you have the price you pay for the goods after the sale is applied.
