The graph shows the price of five gallons of gasoline during the first ten months of the year. By what percent is the highest price more than the lowest price?

图表显示了今年前十个月五加仑汽油的价格。最高价格比最低价格高百分之多少？

(A) 50 50

(B) 62 62

(D) 89 89

(E) 100 100

Answer

Correct choice: (C)

正确答案：（C）

Solution

The highest price was in Month 1, which was $17. The lowest price was in Month 3, which was $10. 17 is $\frac{17}{10}\cdot100=170\%$ of 10, and is $170-100=70\%$ more than 10. Therefore, the answer is $\boxed{\textbf{(C)}\ 70}$

最高价格在第1个月，为$17。第3个月最低价格为$10。17是10的$\frac{17}{10}\cdot100=170\%$，比10多$170-100=70\%$。因此，答案是$\boxed{\textbf{(C)}\ 70}$
