The given pie graphs compare the proportion of total yearly money spending for the five types of categories by a specific UK school in three different years. As an overall trend, it can be seen that the amount of money for teachers had the highest proportion for each year whereas the insurance expenditure was the lowest budget for this school when compared to other spendings at the same years. According to the graphs, in 1981, the teacher salary stood at 40%. Then, it rose to 5% in 10 years and reached 50%. However, its rate went down to 45% at the end of the period. Moreover, there was a dramatic fall in other workers salaries, and it decreased by 5% until 2001. On the other hand, the expenditure on insurance was nearly the same as both 1981 and 1991. It went up only 1%. In contrast, after 1991, it changed dramatically and saw 8% at the end of the year. In addition to this, in terms of the rate of furniture and equipment, there was a rapid decrease, and it saw the dippest point, at 5% in 1991.
