Imagine! You have just started a full-time summer job in an office. It's your first day on the job, and the boss has sent you out to buy lunch for the 23 people who work in the office. It turns out that everyone wants either one hot dog or one hamburger for lunch. You get to Enrico's Express, and Enrico asks you how many hot dogs and how many hamburgers you want. You realize you were so excited that you forgot to write down how many of each you were supposed to get. But you see that hamburgers cost $1.50 each and hot dogs cost $1.10 each (tax included), and that you were given $32.10. Assume that $32.10 is the exact amount needed for your purchase. 1. Figure out, in any way you can, how many hot dogs and how many hamburgers were ordered.
2. Do you think the answer you found is the only one possible? Explain why or why not.
