Question

A suit being sold for $268 has a 33% discount.Find the original cost of the suit.

Answer 1

Let x represent the original cost of the suit.

To calculate the discount, they calculated the 33% of the original price and then subtracted the result from the original price.

To calculate the 33% of any given value you have to do as follows:

33/100=0.33

0.33x → represents the 33% of the original price.

The price with discount was obtained by subtracting the 33% discount from the original price, symbolically:

x-0.33x=268

Clear the value of x:

`\begin{gathered} 0.67x=268 \\ x=(268)/(0.67) \\ x=400 \end{gathered}`

The original price of the suit is $400
