XYZ Manufacturing decides to build a new plant. The plant will cost $20 million today and is expected to have a useful life of 20 years. At the end of year 5, 10 and 15, there will be major renovation expenses of $K each time. The plant will produce level returns of $2.5 million at the end of each year for the first 10 years and $5 million at the end of each year for the second 10 years. Find the maximum value of K that XYZ could pay so that the internal rate of return on its investment is at least 12%. (Round your answer to integer)

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
