Let X be the original price
.05X = first discount
new price is X-.05X
.20(X-.05X) = 2nd discount
new price is X -.05X - .20(X-.05X)
new price = X - .05X -.20X + .01X = X - .24X
equiv discount = .24 = 24%
18.12%
22.5%
21%
No, because successive discounts are taken on the discounted price after the first of the successive discounts. Therefore, 3 successive 5 % discounts will total to a smaller discount than one 15 % discount.
Discount divided by original price gives you a decimal which you then multiply by 100. This equals percent of discount Eg: $15 discount, $80 original price 15 / 80 = 0.1875 x 100 = 18.75%
23.5% if the discounts are taken successively, 25 % if the discounts are taken at the same time. The latter is the less usual meaning of this question.
It is 100*[1 - (1 - 9/100)*(1 - 14/100)] % = 100*[1 - 0.9*0.86] % = 100*[1 - 0.774] % = 100*0.226 % = 22.6 %
If something originally costs £650 (or even $650) with 5 percent off, then its modified price will be equal to 650 x (1 - (5/100)) = 617.50. The discount is therefore equal to 650 - 617.50 = 32.50. Don't forget to include the appropriate unit of currency.
Start with 100. 20% off leaves 80, 15% of 80 is 12, leaving 68, an overall reduction of 32%
You save 15 dollars.
Percent of discount is the percentage of a whole price that is taken off as a discount.
3.29 is 30 percent percent discount of 10.97.
