Hey there. I’ve been working away on this challenge for a bit now and I feel(keyword haha) that I am close to the answer. The 2 main problems I’m having is getting the money from the drawer to subtract despite trying to code it to. My other problem is that I’m not really sure how to return the final answer they require of each bill to give. Any help is much appreciated!
