By the way, my method works and the answer is correct. If you’re going to downvote a free service just because it’s not the method you want, don’t be surprised if fewer people offer to help you. Just a tip.

Cheryl, I am not sure what sets method are, but if you group one each of the balls as a set, you might not reach your solution easily.

1 set = $132

How do you plan to proceed from there?

I still think that eventually you will still have to do Guess and check even along this “set” method.
