The bar chart compares the spending by three income groups on three different types of fast food.

Overall, different income group had different amount of money used on fast foods. It is clear that high income paid the most on fast foods in total and the lowest income group spent the lowest amount.

People in high income group spent the most money. Hamburger was their favorite fast food, about 43 pence per week was paid, compared to more than 30 pence per week spent by average income group on hamburger. Fish and chips were loved in average income people, who paid 25 pence per week on them, while high income group spent much lower, just more than 15 pence. High income people liked pizza more than average income people did, their spending on pizza, at almost 20 pence, doubled that by average income group.

People ate more fish and chips than hamburger and pizza in low income group even though their total expenditure was very low. Their spending on fish and chips was around 15 pence per week, which was much higher than the expenditure on pizza, at around five pence. The figure for hamburger came at closeseccond, at a little bit lower than 15 pence.
