The graph below shows the amounts of waste produced by three companies over a period of 15 years.

The line graph illustrates how much

waste

was generated by three enterprises, namely Companies A,

B

, and

C

over a 15-year period starting from 2000 to 2015. It is noticeable that the amount of

waste

produced by

company

C

registered dramatic upward trends,

while

that of companies A and

B

witnessed a completely opposite trajectory during the surveyed period.

Company

C

, notably, was by far the most important

waste

generation in the final year From the outset of 2000,

waste

production by

company

A was the highest prevalence, accounting for exactly 12

tons

, which was in the region of 4

tons

higher than

waste

output in

company

B

. After that, there was a remarkable decline to nearly 11

tons

in the figure for

company

A in 2005, whilst a sharp increase to around 10

tons

was witnessed in the statistics of

company

B

at the same time.

Subsequently

, both saw sharp decreases, with roughly 8

tons

and precisely 3

tons

respectively in 2015. Commencing from 2000, approximately 4

tons

of

waste

output came from

company

C

, hitting the lowest point in 2000, after which it went up sharply to almost 7

tons

in 2010 before reaching its peak of more or less 10

tons

, accounting for the first rank in

waste

generation by the end of the period
