(typing) We'll also change the expected result variable to true, so we can see how what we get differs from what we expect. Let's run it. (silence) It looks like the discount percentage is resulting in zero when it should result in 0.9. This is likely due to the fact that the discount percentage is an integer, and 100 is an integer.
