Answer = C) the same as one 36 percent discount

Say initial order = 100

Discount 20% = 20

Value = 100 - 20 = 80

Again discount 20% \(= 80 * \frac{20}{100} = 16\)

Value = 80-16 = 64

Total discount = 20+16 = 36

0.8*0.8*x=0.64x from initial value, meaning 0.36 or 36% discount

Two 20 percent discounts is 0.8 x 0.8 = 0.64, which is the same as a 36 percent discount.

Answer: C
