老师好！题目如下： A client invest $40000 in four-year certificate of deposit(CD) that annually pays interest of 7%. The annual CD interest payments are automatically reinvested in a separate savings account at a stated annual interest rate of 4% compounded monthly. At maturity, the value of the combined asset is closest to: A 51 200.00 B 51 903.24 C 58 831.19 答案是B。 每年的interest payment 是2800，计算出EAR为I/Y,用计算器计算，为什么N是4不是48呢？谢谢！
