Question

Find the discount.
Original price: $0.75
Discount: ??
Sale price: $0.15

Answer 1

60% off

Explanation:

Answer 2

80%

Explanation:

0.75 ⇒ 100%

0.15 ⇒ x%

0.75x = 100·(0.15)

0.75x = 15

x = 15/(0.75)

x = 1500/75

x = 20%

100% - (discount) = x%

100% - (discount) = 20%

discount = 100%-20%

discount = 80%
