Assume the following scenario: Bob plans to retire in 15 years from now and wants to have the following stream of CFs after retirement. Monthly payments of $6,000 for 10 years starting right after retirement (the first payment will be at the end of the first month of year 16). He then needs an extra 10000$ with the final payment (that is at the end of the final month of year 25). Starting from year 26 he wants the monthly payments to grow at 0.5% per month for another 15 years. (That is the first payment in year 26 will be 6000*(1+0.005). The APR is 8% with quarterly compounding.

What is the present value (at t = 0) of this plan? please give step by step solution!
