The bar chart highlights data on the amount of money in pence per person per week that people at different income levels in the UK spent on different fast foods in the year 1990, while the line graph illustrates the amount of the same fast foods eaten by the British over a twenty-year period between 1970 and 1990, measured in grams per person.
Overall, it is clear that the largest amount of money was spent on hamburgers in the year given. Moreover, there were considerable upward trends in the consumption of both pizza and hamburgers, whereas the amount of fish & chips consumed witnessed a slight decrease over the period in question.
Regarding the expenditure on fast foods, more than twice as much money was spent on hamburgers (45p) by people with high salaries than on fish & chips and pizza (nearly 18p). In terms of consumers with average income, less money was spent on hamburgers and pizza, which accounted for approximately 33 and 12 pennies, respectively. By contrast, the fish & chips expenses grew to 25p. The most popular fast food among lower class was fish & chips with around 17p expenses, which is almost equal to the amount of money spent on it by higher class. Finally, the spending on hamburgers dropped even more in the case of low-income people, it represented 14p, which was twice the expenditure on pizza (7p).
The amount of fish & chips consumed began at nearly 300 grams in the first year. Subsequently, it gradually declined to a low of 200 grams in 1985 before a slide increase to just over 200 in 1990. Notably, this amount is relatively small compared to pizza consumption (just under 300 grams), considering that spending on fish & chips was higher that year. The hamburgers consumption trend went in the opposite direction. There were just under 100 grams eaten in 1970, and, after a ten-year period of steady rise to roughly 150 grams, it climbed significantly, reaching 500 grams in the last year. Likewise, the amount of pizza consumed had grown slowly from approximately 25 grams to just over 100 by 1985 and then it tripled, peaking at just under 300 in the final year.
