If 2.3 hamburgers can be traded for 3.8 hot dogs, 5.1 liverwurst are worth 2.7 baloney, 3.3 dried beefs are equal to 1.0 hamburger, 4.6 peanut butter & banana are valued at 1.1 baloney, and 7.9 liverwurst will get you 2.5 dried beef? Then how many hamburgers would you get if you tried to trade 12.0 peanut butter & banana sandwiches?
