问题如下:
A sports car, purchased for £200,000, is financed for five years at an annual rate of 6% compounded monthly. If the first payment is due in one month, the monthly payment is closest to:
选项:
A.£3,847.
B.£3,867.
C.£3,957.
解释:
B is correct,
calculated as follows (where A is annuity and PV is present value):
A=[rs/m1−(1+rs/m)mN1]
l=(200,000)⎣⎢⎢⎡0.06/121−(1+0.06/12)12×51⎦⎥⎥⎤
l=(200,000)/51.72556
=3,866.56
请问可以帮忙解释答案中公式的具体理论吗?谢谢
