4.Capitalized cost was computed to be P2M. The structure includes some additional expenses of $100,000 at the beginning of the year for the next 15 years, a renewal cost of P200,0000 would occur in which the expected life of the structure is 5 years. Another cost to consider starting at the end of the tenth year for 20 years is expected amounting to P10,000. If the interest rate is 9% per year, determine the perpetual maintenance of this structure. (15 Pts.)
