Chemical costs associated with a packed-bed flue gas incinerator for odor control have been decreasing uniformly for 5 years because of increases in efficiency. If the cost in year 1 was $100,000 and it decreased by $5,000 per year through year 5, the present worth of the costs at 10% per year is closest to:
(a) $344,771
(b) $402,200
(c) $515,400
(d) $590,700
P = 100,000(P/A,10%,5) - 5000(P/G,10%,5)
= 100,000(3.7908) - 5000(6.8618)
= $344,771
Answer is (a)
