The provided pie charts compare the proportion of people’s food budgets spent on restaurant meals versus home cooking, while the line graph illustrates the number of meals eaten at fast food restaurants and sit-down restaurants.
Overall, it is clear that the percentage of the food budget spent on restaurant meals was the lowest. In contrast, the line graph shows that the number of fast food meals was higher than that of sit-down restaurant meals throughout the period. By the end of the period, however, the proportion of the food budget remained stable.
In 1970, the percentage spent on home cooking was 90%, while only around 10% was allocated to restaurant meals. By 2000, this figure had stabilized to a balanced 50% for both categories, indicating that many people began to save money by reducing their spending on restaurant meals.
According to the line graph, both categories started at the same level in 1970. However, from 1980 onwards, the number of fast food meals experienced rapid growth, while the number of sit-down restaurant meals showed a steady increase.
