a) use only the Total Cost Approach or the Incremental Cost Approach. Don't waste your time doing both Ways For Incremental Cost Approach use the template below You may add any additional lines if needed Item Year Cost Salvage Operating Cost NPV For Total Cost Approach use the template below: Old Machine Item Year Cost Salvage Operating Cost NPV New Machine Item Year Factor Cost Salvage Operating Cost NPV b) Conclusion:Myrtle & Son is considering the purchase of a new high speed machine to replace a machine that was purchased several years ago. Selected information on the two machines is given below: Old New Machine Machine __ _ Required: 3) Compute the total advantage or disadvantage of using the new machine instead of the old machine over the next four years using the NPV method and assuming a discounted rate of 10%. Assume that neither machine will have any salvage value at the end of four years. b) Should we buy the New Machine or keep the old Machine based on NPV. Hint : The Present Value Factor of $1 for year 4 is 0.683 using a discount factor of 10% and the Present Value of an Annuity of $1 is 3.170 for years 1 to 4 using a discount rate of 10% You may use either the Total Cost or Incremental Cost Method for your calculation
