Answer:
Difference between A and B =$42398.5
Process B is better as its PW value is smaller than Process A.
Explanation:
In order to use present worth, both Alternatives must have same time period. Since Process B has 4 years means 16 quarters so we make process A to have 16 quarters two with 2% interest rate per quarter.
Note:
We are going to use Compound Interest tables to simplify our work. Formulas can also be used.
For Process A:
Present value of process A=
Present value of process A=
Present value of process A=-$466,932.5
For Process B:
Present value of process B=
Present value of process B=
Present value of process B=-$424,534
Difference between A and B =(-$424,534)-(-$466,932.5)
Difference between A and B =$42398.5
Process B is better as its PW value is smaller than Process A.
