Question

If I bought a computer for $420. It had been reduced by 25%.

What was the original price of the computer before the reduction?
(If I could get an answer asap that would be great!)

Answer 1

$560

Explanation:

if 25% is the discount than the total of the item after the discount is .75x. So to find the original total we need the equation 420=.75x

first we need to isolate x so we divide both sides by .75, doing this will give us 560= x

to check our answer you need to multiply 560 by .75 (which I got by subtracting the discount, .25, from 1) which gives us our discounted total of $420
