Machine X has a first cost of $70,000 and an operating cost of $21,000 in year 1, increasing by $500 per year through year 5 with a salvage value of $13,000. Machine Y has a first cost of $62,000 and an operating cost of $21,000 in year 1, increasing by 3% per year through year 10 with a salvage value of $2000. If the interest rate is i =10% per year, evaluate which machine must you choose on the basis of:
(a) the present worth analysis,
(b) the conventional B/C analysis
a. PW OF COST IS LESSER FOR X, SO SELECT X
b. CONVENTIONAL B/C RATIO IS MORE FOR X, SO SELECT X
