The pie chart gives information about how much a UK school spent on various costs in the years 1981, 1991, and 2001.
Overall, the teacher’s salary contributed to the biggest cost and insurance the smallest to the school in all the three years.
In all three years, most of the school’s money was spend on giving staff salaries. Though other worker salaries saw a fall from 28% in 1981 to 15% in 2001, spendings on teacher’s salary grew in the same period, starting at 40% in 1991 and ending at 45% in 2001. Spending on resources such as books increased to 20% by the year 1991 but then decreased considerably to 9%.
However, the amount spent on insurance was more or less the same in the first two years and later went up to 8% in 2001. Furniture and equipment contributed as low as 5% in 1991 but rose dramatically in 2001 where it was 23% of the total school budget.
