学习了“利息”这一知识后,莉莉同学打算把积攒的3000元钱存入银行两年,有两种储蓄的方法:一种是存两年,年利率是3.75%;另一种是先存入一年,年利率是3.25%,第一年到期时把本金和利息合在一起,再存入一年。莉莉不知道选择哪种方法得到的利息多一些。下面我们来帮莉莉分析一下。我们知道利息=本金×年利率×年限。根据这个公式可以分别求出两种利息有多少,然后再进行比较。

There are two ways to save: one is to save for two years, the annual interest rate is 3.75%; the other First deposit year, the annual interest rate is 3.25%, the first year when the principal and interest are combined, and then deposited for another year. Lily does not know which method to choose to get more interest. Let’s help Lily analyze below. We know that interest = principal × annual interest rate x years. According to this formula, we can separately find the two types of interest, and then compare.
