Final answer:
To calculate the discounted price of a Harrods Teddy Bear with a 20% off coupon from the original price of £15, you save £3 with the coupon, making the final price £12.
Step-by-step explanation:
If you want to buy a Harrods Teddy Bear that is originally priced at £15 with a 20% off coupon, you first need to calculate how much money the coupon will save you. To do that, convert the 20% discount into a decimal by dividing 20 by 100, which gives you 0.2. Then, multiply the original price of the teddy bear by this decimal:
£15 × 0.2 = £3
So, the coupon saves you £3. Now, subtract the amount saved from the original price to find the discounted price:
£15 - £3 = £12
Therefore, with the 20% off coupon, the cost of the Harrods Teddy Bear will be £12, including tax.
