Final answer:
To find the sale price of an item that is discounted by 20%, multiply the original price by the discount percentage and subtract that amount from the original price.
Step-by-step explanation:
To find the sale price of an item, you need to subtract the discount amount from the original price. In this case, the original price is £37 and the discount is 20%. To calculate the discount amount, multiply the original price by the discount percentage:
Discount amount = £37 × 20% = £37 × 0.20 = £7.40
Now subtract the discount amount from the original price to get the sale price:
Sale price = £37 - £7.40 = £29.60
