The line graph provides an insight into the numbers of meals the average Australian family consumed annually in two types of restaurant over a period of 41 years, beginning from 1970
Overal, it is apparently that both two restaurants experienced a rise in their visits during the time frame. It is also worth mentioning that fast food meals were more common than their sit-down meals counterparts at the end of the period.
Looking closer the the line graph, we can observe that, despite having the same starting point in 1970 with 20 meals per year, fast food restaurants and sit-down restaurants followed two different trajectories. Specifically, in 1980, sit-down meals increased significantly with about 35 ones, which was 5 meals more than that of fast food. However, then, fast food restaurants saw a dramatical surge, surpassing the figures for sit-down restaurants in 1988 with approximately 39 meals per year before reaching a peak of about 119 meals in 2010. We can see that, although sit-down restaurants still observe an upward trend in their consumption at the end of the period, with 60 meals per year, this figure was only half as that of their counterparts
