C. Albert is an avid consumer of two specific services, A and B. The following table shows the total utility (TU) that Albert receives from consuming the services on a monthly basis.
a. Fill in the other columns of the table by calculating the marginal utilities for services A and B and the ratios of marginal utilities to price for the two services. Assume that the price of both services is $5. Be sure to use the “midpoint convention” when you fill out the table.
b. If Albert allocates $100 to spend on both services, how many units will he buy of each?
c. How much will Albert spend on each service at the utility maximizing combination?
d. How much total utility will Albert experience by buying the utility-maximizing combination?
e. Suppose the price of service B increases to $10. How many units of A and B will he buy to maximize his utility now?
f. Draw Albert’s demand curve for service B between the prices of $10 and $5.
