The three pie charts show the changes in annual spending by a particular school in 1981, 1991, and 2001.

The three pie charts reveal how the money was spent on five sections of a specific school in the

years

1981, 1991 and 2001.

Overall

,

it is clear that

the teachers’ salaries section accounted for the biggest

share

of annual spending in all three

years

,

while

insurance stood

last

. Teachers’ salaries are allocated to almost half of the

overall

share

of annual spending in all

years

.

In addition

, the figure for other workers’ salaries decreased generally ranging from 28% in 1981 to 15% in 2001,

while

that for insurance increased slightly from 2% in 1981 to 8% in 2001. It is noteworthy that insurance ranked

last

among all sections in all

years

. The percentage of resources

such

as books that were spent annually was 15% at the first of the period,

then

increased slightly to one-fifth of all

share

in 1981 and after that, it declined to 9% in 2001.

While

the trend of the figures for furniture and equipment was the opposite of the resources. Furniture and equipment comprised the same

share

as resources at the beginning of the period (15%),

then

it moderately declined to 5% in 1991, and

at the end

of the period, it accounted for almost a quarter of the annual spending of a particular UK school.
