Draw a graph representing the supply and demand for Starbucks coffee on South Campus. Because many consumers "need" some form of caffeine throughout the day, make the demand curve more inelastic than the supply curve. Now suppose a tax is placed on Starbucks of $1 per caffeinated drink sold. Show the shift in the appropriate curve and label the four (4) areas of interest on the graph after the tax has been put in place. Lastly, assume the tax corresponds to 5,000 drinks being sold. How much tax revenue is generated from this tax and who bears the greater portion (incidence) of the tax?

I understand how to draw the graph, move the curve, and label the four areas of interest. I'm just a little confused on how to go about the last part: Lastly, assume the tax corresponds to 5,000 drinks being sold. How much tax revenue is generated from this tax and who bears the greater portion (incidence) of the tax?
