Jayesh在一年中,每个月第一天都往建房基金投入250美金.每月回报利率为0.75% 到年底Jayesh 总共在账户上有多少钱(第十三次付款前)?
compound interest
钱= 250*1.0075*(1.0075^12 - 1)/(1.0075 - 1)
=3150.348313
要几位有效数字你自己看吧
geometric progression你总该学过吧.
就是 a ,ar ,ar^2 ,ar^3 ,ar^4……这n个数的和=a(r^n - 1)/(r - 1)
第一个月底=250*1.0075
第二个月底=(250*1.0075+250)*1.0075=250*1.0075^2+ 250*1.0075
……
第n月底=250*1.0075^n + 250*1.0075^(n-1) + ……+250*1.0075
你学过那个公式吧,geometric progression中文是什么我不知道.不过你应该知道,要不,你做这题干嘛
