Remember:
n/100 = is/of
So we want to find the percentage discount, first we get the discount itself.
74.99 - 45.75 = 29.24
29.24 IS the discount OF 74.99
x / 100 = 29.24 / 74.99
Then cross multiply to get
74.99x = 2924
Divide both sides by 74.99
x = 2924 / 74.99 = 38.99
So that's about 39%

Here is what you do:
45.75/74.99 = .61
Now we have to find out how much of a discount this actually was, so:
1 - .61 = .39 x 100 = 39%
39% is your answer.

45.74 / 74.99 = .6101 = .61 = 61%.
Then you have to do 100-61 = 39%.
