The costs associated with the electrical consumption of the console system are the following: The cost of electricity consumption for the complete console system is $ 175 per day, 12 hours per day. Assume that the system will operate for 260 business days annually. Perform a present value analysis to select the best alternative A. Consider that the replacements will be for identical units B. The residual value of the equipment corresponds to the cost of disposal of the unit C. Analyze a 30-year horizon D. Consider an interest rate of 6% installation of a system of individual units consisting of four capacitors and 41 consoles The initial costs are as follows: Cost item Unit Cost Units Total Cost Useful Life Condenser MDV 400 $9,000 2 6 years Condenser MDV 450 2 6 years $9,700 $700 Consoles 12,000 BTU 31 6 years Consoles 19,000 BTU $900 10 6 years n/a Materials*** $35,000 $18,000 Labor for installation n/a concept **** *** Includes materials for the insulation system. The cost of materials for the replacement of the consoles is obviated **** Replacement labor is reduced to 80% of original cost.
