Table 20P-1 shows supply and demand in the market for sub sandwiches in Wheretown, where the local government wants to raise revenue via a $1 tax on all sandwiches, collected from sandwich shops.

a. Graph supply and demand. Before and after the tax: What is the equilibrium quantity? What price is paid by consumers? What price is received by suppliers?
b. Calculate consumer and producer surplus before and after the tax.
c. How much tax revenue does Wheretown receive?
d. How much deadweight loss is caused by the tax?
e. Suppose it costs Wheretown $35 to collect the tax revenue from sub shops. In the end, how much revenue from the sub tax is actually available to spend on public services?
