单选题
If the cost of oil is negligible，what is the mileage(average miles per gallon of fuel)of a compact car? A. 13 B. 18 C. 20 D. 25 E. 28
【正确答案】
C
【答案解析】若Oil的成本可以忽略不计，问每加仑的汽油能使小型汽车运行多少英里? 要算出每加仑的汽油能使小型汽车运行多少英里，就要知道小型汽车每年运行的总英里数及其所消耗的汽油加仑数。题目标题的括号中的“based on 15，000 miles per year”以及题目的尾注中的“Based on $1.50 per gallon for fuel”都是考生应当注意的内容，但考生一定要注意到限制性语言“per year”，因为第一个表格中的花费为“four-year”，找到图表中的第五栏中Fuel/Oil一行，根据Oil可以忽略不计，可得一辆小型汽车4年的Fuel花费用为$4500，由此可得每年的Fuel花费为$4500/4=$1125，而汽油价格为$1.5/gallon，所以每年一辆小型汽车所需的Fuel为$1125/$1.5=750 gallons．每年的总英里数为15，000英里。总英里数除以总加仑数即可得本题的答案：15，000/750=20miles/gallon。
