问题 [br] In how many of the years shown was the number of widgets sold at least three times the number of widgets sold in 1960?
选项 A、Four
B、Three
C、Two
D、One
E、None
答案 D
解析 The correct answer is D. The first step in solving this problem is to calculate three times the number of widgets sold in 1960. According to the graphs, the number of widgets sold in 1960 was 115,000; 115,000(3)= 345,000.
The only year in which more than 345,000 widgets sold was 1980(490,000 widgets sold).
