The given pie chart exhibits the share of the budget of the average family spent on restaurant food. Meanwhile, the line graph illustrates the data about the quantity of ordered meals at two different types of restaurants.
Overall, while the part of budget spent on take away food was the highest in 1990 and 2000, there was an insignificant percentage of family accumulations wasted for ordered dishes in 1970 and 1980. Neverthelss, the popularity of sit-down restraunts had a downward trend mostly, whilst the revenue rate of fast food cafes was increasing troughout the investigated period.
More specifically, it is depicted that in 1970 a simple family used to spent only 10% of income on ordered food, however in a ten-year perion the number rose by 5%. Albeit, in 1990 the average family could spend more than a third of incomes on take away food. Finally, in 1990 a half of average family accumulations was wasted on bills at reastaurants.
In detail, both types of cafes served approximately 20 meals in 1970. Similarly, in 1985 these cafes made equaly 40 dishes each. Albeit afterwards, fast food cafe chains became almost twice as popular as real restaurants in 2000.
