Answer:
$180
Explanation:
Alright, this took me a second of thinking.
So let's say our original price is x. Now to get to the discounted price of 135, we had to take off 25%. Because we know 25% of x is now gone, 135 must be 75% of x. So in this case we would divide 135 by .75 and that would give us 180.
Now to check this out, we just have to remove that 25% and see if we still get 135. So when we multiply 180 x .25 we get 45. Then subtracting our 45 from 180 we get 135, proving that the original price is indeed $180.
