Original price of a computer what is $1250 a year on sale, the selling price of acomputer was $900. find percent discount.

Proof:

1250 - 900 = 350 is the amount saved

350/1250 = 0.28 = 28% is the discount

You take 28% of 1250 to get 350, then subtract off 350 to end up with 900

1250 - (28% of 1250) = 1250 - 0.28*1250 = 1250 - 350 = 900

Or a shortcut is

1250*(1-0.28) = 1250*0.72 = 900

This is because the price is reduced by 28%, so you still pay the remaining 72%
