Marisa White Chapter 11 Question 6

Something that I found interesting was just thinking about how weird it is that every country has a different currency. I feel like it is just a pain to have to convert money since different currency can be worth different amounts. This might be a stupid idea, but I think it would be interesting to see what it would be like if everyone in the world had the same type of money. That seems like it would be more practical and would be one less thing that people would need to worry about. But I am sure there is some sort of reason why it wouldn't work because if it was more simple I feel like that's how it would be.
