The provided bar chart illustrates how much revenue a coffee shop in a British town generated in an average month from six menus in 2000, 2010, and 2020. Units are measured in pounds sterling.
Overall, coffee consistently generated the highest sales in all three years, while soup brought in the least income. Although there was a slight decline in soup sales over the two decades, earnings from other categories experienced a significant rise.
Revenue from coffee increased from 1,500 pounds per month in 2000 to nearly 2,300 pounds in 2020. Likewise, income from tea and hot chocolate climbed by almost 700 pounds, reaching approximately 1,700 pounds each by 2020.
Monthly sales of sandwiches and cake also grew modestly, rising from just over 500 pounds at the start of the period to about 1,000 and 1,200 pounds, respectively, in 2020. On the other hand, soup revenue fell, decreasing by half to finish at approximately 200 pounds in the final year.
