original price and discount as a percent

Question

Locate a sale television. Choose one television that is on sale. Note the original price and the discount as a percent. Find the saving in dollars and cents on the purchased of this television.

Answer 1

When you find your TV take the sale price (x) and divide it by the original price (y). Then take your quotient and multiply it by a factor of 100. Then subtract your percent  from 100 to get percent of the sale

 

Expressed as so:

 

x/y=z. Z*100=z%. 

 

100-z%=%off

 

So if the tv is 10 dollars but originally cost 15 then 

 

10/15 = .667. 

.667*100= 66.7%

 

100-66.7%=33.3% off the original price
