Question

Discount? When the original price is $0.75. And the sale price is $0.15.

I'll make it a pretty high poin value!

Answer 1

we know

SELLING PRICE= MARKET PRICE- DISCOUNT

0.15/- = 0.75/- - X% OF 0.75

X% OF 0.75 = 0.60

THEN

(X÷100)*(75÷100)=(60÷100)

(X÷100)=(60÷100)*(100÷75)

X=(4÷5)*100=80%
