第1题的前半句"brought"是不是多打了个"r"？应该是"bought"吧。
题1前半句：Leo买了一张面值为$10,000的1年期存款单。该存款单的年利率为8%，每半年支付一次利息。
注释：
certificate of deposit：存款单
annual rate：年利率
compound semiannually：半年付息
题2：在最近一次的旅程中，Cindy的车行驶了290英里（四舍五入到了十位），耗油12加仑（四舍五入到了个位）。Cindy的车每消耗1加仑汽油所对应的实际行驶的英里数应该介于多少之间？
1。Leo 买了一个半年转期复利的$10,000存款，存期一年。。。
2。最近 Cindy 去旅行了一次，如果按个位四舍五入，她驾驶了290 英里，如果按四舍五入到个位，她使用了 12 加仑汽油。。。
第二题答案应该是 285/12.5 and 295/11.5吧
英里是按照十位数来四舍五入的。所以取285到295之间。同理汽油取11.5到12.5
