Answer:
The present worth of all costs for the newly acquired machine is determined to be $131,097.89.
Explanation:
Note: See the attached excl file for the calculation of the present worth of all costs for the newly acquired machine (in bold red color).
In the attached excel file, the following formula are used:
1. From Year 6 to Year 13, Annual operating cost for the current year = Annual operating cost for the previous year * (1 + Growth rate) = = Annual operating cost for the previous year * (1 + 10%)
2. Discounting Factor = 1 / (1 + r)^n .............. (1)
r = interest rate per year = 10%, or 0.10
n = each particular year being considered
From the attache excel, the present worth of all costs for the newly acquired machine is determined to be $131,097.89.
