Cindy has her eye on a sundress but thinks it is too expensive. It goes on sale for 15% less than the original price. Before Cindy can buy the dress, however, the store raises the new price by 25%. If the dress cost $68 after it went on sale for 15% off, what is the difference between the original price and the final price?

Respuesta :

Answer:

Difference between  Prices= $85-$80

Difference between Prices=$5

Explanation:

First we will calculate the original price of the dress. In order to do this we will proceed as follow::

After Sale for 15% off price of dress =$68

[tex]Original Price *\frac{85}{100}=68[/tex]

[tex]Original Price=\frac{68*100}{85}[/tex]

Original Price=$80

Before buying prices rises by 25%.

Rises and discounts making the Final Price=[tex]68*\frac{125}{100}[/tex]     Note:    (125 is due to 25% rise)

Final Price=$85

Difference between  Prices= $85-$80

Difference between Prices=$5
