Final answer:
Pharoah Company should replace the old machine with the new machine, as it has a lower total cost than retaining the old machine.
Step-by-step explanation:
To determine whether Pharoah Company should retain or replace the old machine, we need to compare the costs of the two options. The old machine has a book value of $169,000 and a remaining useful life of 6 years. The new machine costs $246,500 and has a 6-year useful life with no salvage value. The new machine will lower annual variable manufacturing costs from $595,000 to $495,000.
In order to analyze the costs, we need to calculate the total cost for each method. For the old machine, the total cost would be the annual variable manufacturing costs of $595,000 multiplied by the remaining useful life of 6 years, which equals $3,570,000. For the new machine, the total cost would be the cost of the machine, which is $246,500. Therefore, the total cost for the new machine would be $246,500.
Based on this analysis, Pharaoh Company should replace the old machine with the new machine, as it has a lower total cost than retaining the old machine.
