Question

Question 1 0.45 pts Mr. Asimov must replace the 11 robots on his assembly line. The Robo 100 model costs $28,663 per robot and they will last for three years. The EconoRobo model costs $11,072 per robot and will last for two years. The Robo 100 models will have an end of life salvage value of $9,486 each. The EconoRobo models will not have any value at the end of their lives. The Robo 100 models are also more energy efficient and it is estimated Mr. Asimov will be able to save a total of $3,865 per year in energy costs. Mr. Asimov uses a MARR of 10% to evaluate potential investments. Using present worth analysis, what is the present worth of the Robo 100 system? Notes: Assume all robots on the assembly line are replaced. Enter your answer as: 1234 Round your answer. Do not use a dollar sign ("$"), any commas (.') or a decimal point("").

Answer 1

Robo 100 cost a $28,663 Total cost a $28663 x 11 24315293 Salvage value $9486 each Total salvage value - $9486x 11 - 8104346 Total savings on new system @ 3865 / year Present worth of Robotoo systems, Roboloo 2 - $315293 - $315293(/F,10%, 3)+ 3865 (C/A,10%,6) +104346(%/,107,3) + 104346[8/, lo'), 6) 2-315293 - 236785.043 +16833.2345+78363.846 + 58851.144 z — 398029.8185 F-398030] Is the rounded correct answer.
