The pie charts compare the alterations on the yearly expenditures of a specific school in the UK between 1981, 1991 and 2001. It is keenly observed that manpower salaries dominated the most annual spending in the given time frames. In 1981, precisely 40% of the annual expenses was spent on the teacher' s salaries with an increase of 10% ten years thereafter, before decreasing by 5% in 2002. Other worker' s salaries were also high which comprised of more than a quarter in the beginning but eventually went down by almost half in the final year. While the other manpower' s salaries dropped, the cost of insurances rose by fourfolds. Furniture and equipment, meanwhile, accounted at 15% in 1981 which was the same with the expenditures on resources such as books. Afterwhich, the former declined three times while the latter went up at 20%, before a remarkable growth of 23% and a substantial drop of 9% respectively.
