The Cebu City plans to increase the capacity of her existing water transmission lines. Two plans are under consideration. Plan A requires the construction of a parallel pipeline, the flow being maintained by gravity. The initial cost is P151,582,222 and the life is 40 years, with an annual operating cost of P6,350,911 for the 1st 20 years and P14,898,843 for the next 20 years. Plan B requires the construction of a booster pumping station costing P100M with the life of 40 years. The pumping equipment cost an additional amount of P25M, it has a life of 20 years and a salvage value of P2M. The annual operating cost is P5M. Using the Present Value (PV) Method and an interest of 22% cpd. annually, what is the PV of Plan A?
initial cost is P151,582,222--------------------------------(I)
annual operating cost of P6,350,911 for the 1st 20 years and P14,898,843 for the next 20 years.
Interest rate (r) = 22%.
Formula-
Peset value of the Annuity =
A= Annuity payment
r= interest rate
n= number of year
Present value of the First 20 payments=
=>Present value of the First 20 payments= P28,326,753--------------------------(II)
value of the LAST 20 payments at the end of 20th year =
=> value of the LAST 20 payments at the end of 20th year=P 66,452,804
as we konw PV =
Hence Present value of the LAST 20 payments now =
=>Present value of the LAST 20 payments now=P 1,245,422------------------------(III)
Hence total pv of plan A (I+II+III)= P151,582,222+P28,326,753+P1,245,422=P 181,154,397
