Question

7. An industrial firm uses an economic analysis to determine which of two different machines to purchase. Each machine is capable of performing the same task in a given amount of time. Assume the minimum attractive rate of return is 8%. Use the following data in this analysis. Machine X Machine Y $12,000 13 $4000 $175 Initial cost Estimated life (years) Salvage value Annual maintenance cost Which machine should the firm choose and why? A) machine X because (EUAC)x(EUAC) C) machine Y because (EUAC) (EUAC) D) machine Y because (EUAC)>(EUAC) $6000 $150

Explanation / Answer

Solution: Machine X because EUACx < EUACy

Working:

EUACx = $6,000 (A/P,8%,7) + $150 = 1302

EUACy = ($12,000 - $4,000) (A/P,8%,13) + $4000* 0.08 + 175 = 1507.17

Select Machine X because EUACx < EUACy
