A specialty concrete mixer used in construction was purchasedfor $300,000 7 years ago. Its annual O&M costs are$105,000. At the end of the 8-year planning horizon, the mixer willhave a salvage value of $5,000. If the mixer is replaced, a newmixer will require an initial investment of $375,000. At the end ofthe 8-year planning horizon, it will have a salvage value of$45,000. Its annual O&M cost will be only $40,000 dueto newer technology. Analyze this using an EUAC measureand a MARR of 15% to see if the concrete mixer should bereplaced if the old mixer is sold for its market value of$65,000.
(a) Use the cash flow approach (insiderâs viewpoint approach)and show the EUAC values used to make your decision:
(i) Existing concrete mixer: $
(ii) New concrete mixer: $
(b) Use the opportunity cost approach (outsiderâs viewpointapproach) and show the EUAC values used to make your decision:
(i) Existing concrete mixer: $
