Question

Della bought a dress at 20% discount sale for $57.60. Find the original price of the dress.?

Answer 1

The original price of the dress is `$72`

Explanation:

Let us assume the original price to be `x`.

According to the question,

`x-20%xxx=$57.60`

`x-(2cancel0)/(10cancel0)xxx=$57.60`

`x-(cancel2^1)/(cancel10^5)xxx=$57.60`

`5/5x-1/5x=$57.60`

`4/5x=$57.60`

`x=$57.60xx5/4`

`x=$72`

`therefore` The original price of the dress is, therefore, `$72`

Answer 2

`P_o=$72`

Explanation:

This problem requires you to set up an equation that relates the original price to the sales price.

You have the discount rate, the sales price, and you need to find the original price.

Remember, you also must know that if something is sold at a 20% discount, the price is 80% of the original.

Now, you can set up your equation.

`80%*P_o=P_f`

`P_o=($57.60)/(80%)`

`P_o=($57.60)/.8`

`P_o=$72`

Your original price is 72 Dollars
