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 5.70 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 banks annual operating costs into four activities.

B. Compute the profit from Customer A and Customer B, assuming that customer costs are based only on deposits. Interest costs = {{0.5:#,##0.00}} percent of deposits; operating costs are 4 percent (= $22,500,000/$562,500,000) of deposits. (Do not round intermediate calculations. Round your answers to 2 decimal places.)
