Mistake in the MiniProblem?
-
On the miniproblem from Challenge Explanation 5 for Day 10, I think there might be a mistake. The solution says to add the equations and I got 4a+4b+4c+4d+4e, however, the solution gets 3a+3b+3c+3d+3e. Can anyone check or confirm?

@wisegiraffe Same! I tried it and got d=3.75. I noticed this too!
