ABC Ltd. purchased a new 3-D printer for $500,000 at the beginning of year 1. Although this printer is expected to last for 10 years, ABC knows the technology will become old quickly, and so they plan to replace this printer in 4 years. At that point, ABC would be able to sell the printer for $20,000. Calculate the net book value of the printer when at the end of year 2 using the declining balance method with a rate of 50%.

Aproduction line has three machines a, b, and c, with reliabilities of .96, .86, and .85, respectively. the machines are arranged so that if one breaks down, the others must shut down. engineers are weighing two alternative designs for increasing the line’s reliability. plan 1 involves adding an identical backup line, and plan 2 involves providing a backup for each machine. in either case, three machines (a, b, and c) would be used with reliabilities equal to the original three. a. compute overall system reliability under plan 1. (round your intermediate calculations and final answer to 4 decimal places.) reliability b. compute overall system reliability under plan 2. (round your intermediate calculations and final answer to 4 decimal places.) reliability c. which plan will provide the higher reliability? plan2plan1
