The pan american bottling co. is considering the purchase of a new machine that would increase the speed of bottling and save money. the net cost of this machine is $66,000. the annual cash flows have the following projections. use appendix b and appendix d for an approximate answer but calculate your final answer using the formula and financial calculator methods. year cash flow1 $24,0002 $25,0003 $28,0004 $16,0005 $9,000a. if the cost of capital is 8 percent, what is the net present value of selecting a new machine? b. what is the internal rate of return?

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
