1. An automaker is considering installing a three-dimensional (3-D) computerized car-styling system at a cost of $240,000 (including hardware and software). With the 3-D computer modeling system, designers will have the ability to view their design from many angles and to fully account for the space required for the engine and passengers. The digital information used to create the computer model can be revised in consultation with engineers, and the data can be used to run milling machines that make physical models quickly and precisely. The automaker expects to decrease the turnaround time for designing a new automobile model (from configuration to final design) by 22%. The expected savings in dollars is $209,000 per year. The training and operations and maintenance cost for the new system is expected to be $51,000 per year. The system has a five-year useful life and can be depreciated according to the five-year MACRS class. The system will have an estimated salvage value of $6,000. The automaker's marginal tax rate is 34.4%. Compute the rate of return of the project. Enter your answer as a percentage between 0 and 100.

2.The Columbus Electrical Company expects to have an annual taxable income of $726,000 from its residential accounts over the next two years. The company is bidding on a two-year wiring service for a large apartment complex. This commercial service requires the purchase of a new truck equipped with wire-pulling tools at a cost of $60,000. The equipment falls into the MACRS five-years class and will be kept for 10 years. The project will bring an additional annual revenue of $291,000, but it is expected to incur additional annual operating costs of $137,000. Using the Corporate Tax Schedule on Table 9.12, what is the total amount that Columbus Electrical will have to pay in taxes in year 2 if the company decides to work on the project?
