1.you want to buy a car and need to choose between the low finance rate and the cash duscount. In the first option, you can enjoy the 3% APR financing for 48 months. In the second option you face a 7.2%APR loan for 48months but can get a cash reward of 15000 for the down payment. If the car is worth 250000 which option you will choose? please find the difference in the monthly payment between the two choices. 首先第一個問題答案給的option 2的算法為第一期可獲得cash reward 15000 所以250000-15000/(1+7.2%/12)=PMT*PVIFA(7.2%/12,48) 得到PMT為5651.35 但我認為cash reward應該是在一開始就扣掉而非第一期所以我的算法: 250000-15000=PMT*PVIFA(7.2%/12,48) 求得PMT=5649.2 因為題目並未提到cash reward是在第一期所以關於這點我在想是不是答案有問題在來題目問兩個方案該選哪個我認為第一個方案的現值為250000 第二個方案的現值為250000-15000=235000 所以應該選第二個因為較便宜但答案中是解釋因為option 1算出來的PMT=5533.58 比option 2的PMT小所以選方案一而我們在做決策時不是應該根據淨現值(NPV)大小來決定嗎? 是我的想法有誤還是答案錯了? 煩請各位高手幫我解答謝謝!! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 111.254.137.101
