The provided graphs illustrate the differences among the annual expense of a British school in three distinct years. In general, the greatest expenditure was on staff salaries and it stayed steady through the mentioned period. Meanwhile, the insurance had the smallest amount of money spent on but it eventually rose. To describe in details, the teachers’ paychecks accounted for the highest percentage of the school budget and peaked at 50% in 1991. The figures for this particular cost remained fairly constant around 40% and 45% over the years. In contrast, the investment in other workers’ wages was considerably lower. It saw a serious fall starting from 28% in 1981 and reached a trough at 15% in 2001. According to the data, there was a fluctuation in the proportion of annual costs for furniture and equipment. First it dramatically decreased to 5% in1991 and then rose up to 23% in 2001. In addition, the two remaining areas of spending both showed the same rising trend. For example, the percentage of the resources like books gradually increased from 15% up to 23%. Although the least amount of money was spent on insurance over the two decades, a serious growth still can be seen. The initial 2% in 1981 quadrupled at the end of the examined period in 2001.
