The bar chart shows how much money was spent on fast foods per week in the UK over a span of 20 years from 1970 to 1990 while the graph reveals the trend of fast food consumption over the same period of time.
As we can see from the chart, the weekly expenses of people of different income levels on hamburgers and fish and chips were relatively higher than that on pizza. The graph indicates that while hamburger and pizza consumption both revealed a general trend of increase, fish and chips showed a trend of fluctuation.
First, the weekly average expenses of high-income people and middle-income people were 42 pence and 33 pence respectively, a lot higher than that of low-income people which was 14 pence. As for fish and chips, high-income people spent relatively less, only 17 pence, but the expenses of middle-income and low-income groups reached 25 pence and 18 pence, much higher than their expenses on pizza which stood at 12 pence and 8 pence respectively. What is worth mentioning is the amount of money spent on pizza by high-income people which showed only 20 pence, 2 pence more than their expense on fish and chips.
