HELP! FOR 100 POINTS

In a sale, all prices are reduced by 22%. A pair of trainers normally cost £80. What is the sale price of the pair of trainers?

Answer 1

Answer: $62.40

Explanation:

Original price $80

22% of 80%

.22(80) = 17.60 >This is the discount

Sale price = Original price - discount

Sale price = 80 - 17.60

Sale price = $62.40

Answer 2

`\Huge \boxed{\text{\$62.40}}`

Explanation:

In the sale, the prices decrease by 22%. This means that the sale price is 78% of the original price.

`\Large \text{Sale price = (100 - 22)\% of old price}\\\text{Sale price = 78\% of \$80}\\\text{Sale price = 0.78 $*$ 80}\\\text{Sale price = \$62.40}`
