You’ve been working on Problem 1.

Problem 1. You have your friend roll three dice, without showing you the outcome. You then ask her to multiply the number on the first die by 5, then add 7 and double the result, add the number on the second die, multiply this result by 10, add the number on the third die, and tell you the result. If her result is 401, what were the numbers (in order) on the three dice?
