Compare the alternatives C and D on the basis of a present worth analysis using an interest rate of 14% per year and a study period of 10 years. Alternative First Cost AOC, per Year Annual Increase in Operating Cost, per Year Salvage Value Life, Years C $-48,000 $-9,000 $-1,400 $8,000 10 The present worth of alternative C is $-117974.14 Alternative D offers the lower present worth. D $-34,000 $-9,000 $-1,500 $1,400 5 and that of alternative D is $ -73129.34

Compare three mutually exclusive alternatives on the basis of their capitalized costs at i =10% per year. Alternative |First cost, $ AOC, $/year Salvage value, $| Life, years B2 300,000 |-10,000 |70,000 A1 -50,000 C3 |-30,000 5,000 2 900,000| 3,000 |200,000

Given the data for three different alternatives in the table below, determine the best alternative using the incremental rate of return (∆RoR) analysis. MARR =9%.     A B C First cost $15,000 $25,000 $20,000 O &M Cost/ year 1,600 400 900 Benefit/year 8,000 13,000 9,000 Salvage value 3,000 6,000 4,600 Life in years 4 4 4   The better alternative between the second  increment (B – C) is:. Group of answer choices Alt. B Alt. C Alt. B or Alt. C Alt. A
