NO.PZ2015120604000015问题如下 investor is looking a house worth $ 2.5 million. If he want to buy the house, he must p25% of the full prinow anthe left money is finance10%，compounmonthly over the next 25 years, Calculate the monthly mortgage payment in this case. A.$17,850 B.$22,607 C.$17,038 C is correct.N = 25 × 12 = 300;I/Y = 10 / 12;PV = -2,500,000(1 - 0.25) = -1,875,000 (75% of the full prileft);FV = 0;CPT PMT = $17038 N=300，利率0.83不变，PV是625000（首付），FV为2500000，然后求PMT，这个思路就是当下我先付625000然后每个月付多少钱能满足25年后用付了2500000，求PMT
