问题 If the increase in the number of students enrolled from 1950 to 1960 was half the increase from 1960 to 1970, what was the student enrollment in 1950?
The increase in tuition per student from 1970 to 1980 was approximately how many times as great as the increase from 1960 to 1970?

选项 A、2
B、2.5
C、3
D、3.5
E、4

答案C

解析 1970至1980年每个学生的学费增长额大约是1960至1970年的多少倍?
解：本题的正确答案为(C)。由表可知，1960、1970和1980三年每个学生的学费分别为$1400，$2000和$3700，因此增长倍数为($3700-$2000)/($2000-$1400)≈3。
