1. Draw a graph with the price of a cup of coffee on the vertical axis and quantity on the horizontal axis. At $10/cup how many cups will you purchase each week? At $5/cup how many will you purchase? How about at $1.00/cup? (If you don't drink coffee choose something else that you purchase several times a week -- hamburgers, gum, etc.) Does you demand curve slope downward and to the right? Why?
2. A change in something other than price will shift your demand for coffee - give me an example of something that might shift your demand for coffee. For example, if you get a big raise at work will you purchase more cups of coffee even if the equilibrium price doesn't change?
3. Now pretend you are the owner of a coffee shop. As the price of a cup of coffee rises are you willing to supply more cups of coffee to the market? Why or why not? If your answer is yes, that leads to an upward sloping supply curve. Why might a rising price be required to supply more of a good? What might cause the supply curve to shift?
4. And that gets us to equilibrium. Put both your demand for cups of coffee and the supply on a single graph. Define equilibrium. Why can't coffee suppliers charge whatever they want for a cup of coffee?
