Yes - that's a mistake indeed. You can also notify PrepLounge on the ‘Support’ button on the left hand side of the screen so the case can be adjusted.

You're absolutely right! While it's not ideal, there will always be a subset of exercises/cases that have some math mistakes.

If/when you spot them, if you logic through and can confirm they're not correct, then make a note and move on/forward!
