Q.4 (25pts) Sandersen Meat Processors has asked its lead process engineer to evaluate two different types of conveyors for the beef cutting line. Type A has an initial cost of $82897 and a life of 4 years. Type B has an initial cost of $97452 and a life expectancy of 6 years. The annual operating cost (AOC) for type A is expected to be $8194, while the AOC for type B is expected to be $7056. If the salvage values are $5533 and $10555 for type A and type B, respectively, tabulate the incremental cash flow using their Least Common Multiple (LCM).
The life of the different conveyors for the beef cutting line is not equal. So, use the common multiple method and convert the unequal life to equal life. Type A has a life of 4 years and Type B has a life of 6 years. The LCM of 4 and 6 will be 12. So, the common life of both the alternatives will be 12 years.
Plan A – Is to be repeated for 3 times (0th, 4th and 8th year)
Plan B – Is to be repeated for 2 times (0th and 6th year)
The other information is as given

Plan B |
Initial Cost = -82897 Annual Operating Cost = -8194 Salvage Value = 5533 |
Initial Cost = -97452 Annual Operating Cost = -7056 Salvage Value = 10555 |
Now, tabulating the incremental cash flow using the least common multiple.
The incremental cash flow will be calculated for Plan B – Plan A
