Club Penguin Percentage Not Equal BUG

While collecting items on my new Test penguin to test out bugs. I recently just found a BUG with the Coins For Change Percentages The percentages are supposed to be equal to 100%. Some penguin didn't remember that or didn't think about that and made the percentage 101%. :|

I think some penguin needs a math lesson. 40%,31%, and 30% obviously don't add up to 100%. This is now a BUG for Club Penguin. Next time they need to check their math.
