I would really appreciate help on the below question. I know it is a CR question but my problem is understanding how the thought process works.
Q 42: In the state of Michigan, from 1980 to 1989, total spending on books purchased from all sources increased by 34 percent. But during the same period, spending on fiction books, most of which were purchased from bookstores selling only new books, grew just 16 percent.
Which of the following statements about the period from 1980 to 1989 is best supported by the statements above?
Answer: Spending on nonfiction books increased by more than 34 percent.
How do you know it is definitely more than 34 percent? I know this is a CR question but I'm having trouble understanding the math part of it. I don't understand how the increase can be more than 34 percent or how it was worked out. Please help and thank so much in advance.
