The three pie charts indicate the figure of annual spending by a certain British school in 1981, 1991 and 2001 respectively.
As is the case with teachers` salaries occupied the largest percentage in 3 years while the cost in insurance produced the smallest. However, the proportion of insurance spending was increasingly high.
In 1981, the school spent 40% cost on teachers` salaries, followed by other workers` salaries (28%). In terms of resources and furniture and equipment, both of them cost the same, with 15%. Spending in insurance only made up 2%.
After a decade, the costs of teachers` salaries and resources increased 10% and 5% respectively, while there were decreases in those of other workers` salaries and furniture and equipment.
Compared to those of 1991, the spending of salaries and resources dropped by the range of 5% to 10%. By contrast, costs in other two aspects, insurance and furniture and equipment, raised dramatically, constituting 8% and 23% respectively.
