问题 [br] Approximately what is the percent increase in the number of Master Cleanse dieters from 1995 to 2000?
选项 A、200%
B、157%
C、189%
D、187%
E、129%
答案 C
解析 The correct answer is C. In 1995, 0.07×135, or 9.45 million people were on the Master Cleanse diet. In 2000, 0.13×210, or 27.3 million people were on it. The difference between the two numbers is 17.85. So the fraction is the difference over the original, or, which simplifies to 1.88888 or 1.89.
