By approximately what percent did the sale of nonfiction titles increase from 1984 to 1987?
A. 42%
B. 50%
C. 70%
D. 90%
E. 110%
According to the undashed line on the chart:
Nonfiction in 1984 = 40%.
Nonfiction in 1987 ≈ 58%.
Thus:
Percent increase from 40 to 58 = (difference/original) * 100 = (18/40) * 100 = 45%.
The correct answer is
A.
