Rock Solid Bank and
Trust (RSB&T) offers only checking accounts. Customers can
write checks and use a network of automated teller machines.
RSB&T earns revenue by investing the money deposited;
currently, it averages 5.40 percent annually on its investments of
those deposits. To compete with larger banks, RSB&T pays
depositors 0.50 percent on all deposits. A recent study classified
the bank’s annual operating costs into four activities.

Required:
a. Compute RSB&T's operating profits.
b. Compute the profit from Customer A and Customer B, assuming that customer costs are based only on deposits. Interest costs = 0.50 percent of deposits; operating costs are 4 percent (= $18,000,000/$450,000,000) of deposits.
c. Compute the profit from Customer A and Customer B, assuming that customer costs are computed using the information in the activity-based costing analysis.
