Problem 102 asks for the PW of the investment and maintenance cost. In the solution, I understand the first equation is a "single payment PW" equation for one system, and the second and third equation of the solution is a "uniform sreies PW" equation.
Please help me understand where the "20,000" in the second equation and the "10,000" in the third equation comes from.
Please help me understand why the first and third equation is calculated for "2 years", and why the second equation is calculated for "4 years".
Thank you in advanced for any help provided.
