题目

原题就是这么写的,我有点没看懂.：
suppose upon graduation from college a relative gives you $20000 to buy a car.You find a car you want,and the delership gives you a choice between :$1000 cash back,or $500 cash back plus 0% financing for 36 months.you currently are keeping 20000 in an account that earns 3% interest,compounded monthly.Which is the better offer?

答案

如果大学毕业后你亲戚给你20000美元买一辆车.你找到你想要的车,提供给你2个选择：1000美元的现金,或现金500美元,36个月后再加上0%的融资.您目前的帐户保持20000的利息收入3%,月复利.这是更好的报价吗?第一种：花了1k,剩一万9.19000*1.03^36=55067 第二种我不太理解 0% financing for 36month的意思~如果不管他,那么第二种是19500*1.03^36=56516.所以选择第二种
