A store is having a 10% off sale. It gives an additional 20% off for an item that is above $100 after the first 10% discount.A jacket costs $124.99

Answer 1

124.99 / 100 = 1.2499 (This is 1% of the price)

1.2499 * 10 = 12.499 = 12.50 (This is 10% of the price)

so you minus the price with 10%

124.99 - 12.50 = 112.49 is the price after 10% discount

now to get the further 20% off the price you will use the same method to work out 20% of the price and then minus the price with 20%.

112.49 / 100 = 1.1249 (This is 1% of the price)

1.1249 * 20 = 22.498 = 22.50 (This is 20% of the price)

You minus the price with 20%
so you will get

112.49 - 22.50 = $89.99 is the total price after all discounts

so the total amount you would have saved would be worked out by getting the original price and minus it by the price after all discounts
so you will get

124.99 - 89.99 = $35 is the total amount you will save

hope this helps you understand
