Suppose that Devon’s landlord starts charging a $5 fee for each haircut Devon provides, and that nothing else changes.

a. Make a table showing Devon’s new marginal cost for each of the first 4 haircuts. You can determine Devon’s original marginal cost for each haircut by looking at the height of his supply curve in Figure 4.3.

b. Make a table showing Devon’s new supply schedule; include quantities for each of the prices listed in Table 4.1.

c. Draw Devon’s original supply curve and his new supply curve after he must pay his landlord $5 per haircut.

In Table 4.1
