(a)
Calculate the equivalent annual worth.
(a)
Explanation of Solution
Model G: First cost (C) is $36,000. Operating cost (A) is $4,000. Salvage value (SV) is $15,000. Time period (n) is 3 years. Interest rate (i) is 15%.
Model F: First cost (C) is $32,000. Operating cost (A) is $3,100. Salvage value (SV) is $15,000. Time period (n) is 4 years. Interest rate (i) is 15%.
The equivalent annual worth of Model G (AWG) can be calculated as follows:
The annual worth of Model G is -$15,447.48.
The equivalent annual worth of Model F (AWF) can be calculated as follows:
The annual worth of Model F is -$11,304.54. Since the annual worth of Model F is greater than Model G, select Model F.
(b)
Calculate the present worth.
(b)
Explanation of Solution
The time period to calculate the present worth is 12 years
The present worth of Model G is -$83,734.64.
The present worth of Model F (PF) can be calculated as follows:
The annual worth of Model F is -$61,277.41.
