Answer 1

$320

Explanation:

Answer 2

a) 80% b) $80 c) $ 320

Explanation:

Let the original price be $ 100

Discount= 20%

Hence, the selling price is= $ 100 ×
`(100- 20)/(100)`

Hence, the selling price is= $ 80

let selling price x % of original price

$ 80=
`(x)/(100)` × 100

x = 80%

Selling price is 80% of original price

b) If the original price= $ 400

Discount = $ 400 ×
`(20)/(100)` 80

Discount =$ 80

c) Selling price= $ 400
`((100-20))/(100)`

Selling price= 4× 80

Selling price= $320
