Sometimes when we go shopping, we can use discount vouchers or coupons to save money.
Some coupons give a fixed amount of discount provided that you spend at least a certain minimum amount.
Some coupons give a percentage off.
Jack buys a book for £22.40.
Which of these two coupons would be better for him to use to get the better discount.
£22.40 is more than £20, so he will get a £5 discount if he uses the orange £5 off coupon.
25% is the same as a quarter.
2240 ÷ 4 = 560
So he will get a £5.60 discount if he uses the blue 25% off coupon.
The blue 25% coupon gives the better discount.
If he uses the blue coupon, he will have to pay £22.40 - £5.60 which is £16.28
Let's have a go at some questions now.
