money spent on books
The line graph illustrates how much money people spend on three types of books over a period of four years from 2002.
Looking at the graph, it is immediately obvious that the expenditure on children's books and educational books had an upward trend whereas those of adult fiction decreased during the observed period.
In 2002, people spent the most on adult fiction and reached 45 million dollars. This was significantly higher than that of children's books and education books, which was 35 and 25 millions dollars respectively. Then yearly spending on adult fiction reduced to 38 million dollars in 2003. Although its sales rose slightly by 2 million dollars, it continued to fall and stood at 30 million dollars at the end of the period.
By contrast, the payment for two kinds of remainder books experienced a growth of nearly 10 million dollars from 2002 to 2003. In the next two years, while sales of children's books modestly went up, there was a decline of 6 million dollars in the spending on educational books. Between 2005 and 2006, the amount of money pay for them rose gradually.
