1. The charts below show the percentage of their food budget the average family spent on restaurant meals in different years. The graph shows the number of meals eaten in fast food restaurants and sit-down restaurants.You should write at least 150 words.Give reasons for your answer and include any relevant examples from your own knowledge or experience.Over the past 30 years, the average family has dramatically increased the number of meals that they eat at restaurants. The percentage of the familys food budget spent on restaurant meals steadily climbed. Just 10 percent of the food budget was spent on restaurant meals in 1970, and 15 percent in 1980. That percentage more than doubled in 1990, to 35 percent, and rose again in 2000 to 50 percent.Where families eat their restaurant meals also changed during that 30-year period. In 1970, families ate the same number of meals at fast food and sit-down restaurants. In 1980, families ate slightly more frequently at sit-down restaurants. However, since 1990, fast food restaurants serve more meals to the families than do the sit-down restaurants. Most of the restaurant meals from 2000 were eaten at fast food restaurants. If this pattern continues, eventually the number of meals that families eat at fast food restaurants could double the number of meals they eat at sit-down restaurants.(164 words)2. The table below shows the sales at a small restaurant in a downtown business district.Summarize the information by selecting and reporting the main features, and make comparisons where relevant.You should write at least 150 words.Give reasons for your answer and include any relevant examples from your own knowledge or experience.Sales: week of October 7-13Mon. Tues. Wed. Thurs. Fri. Sat. Sun.Lunch $2,400 $2,450 $2,595 $2,375 $2,500 $1,950 $1,550Dinner $3,623 $3,850 $3,445 $3,800 $4,350 $2,900 $2,450model answer:The sales at this small restaurant during the week of October 7 to 13th followed a fairly set pattern from Monday to Friday, and then showed notable shift on the weekend. The lunch and dinner sales during the week peaked on Friday and then dipper down as the weekend set in.During the week of October 7-14th, the lunch sales averaged at approximately $2,400. The highest lunch sales occurred on Friday, and the lowest occurred on Sunday. Sundays lunch sales were approximately $1,000 less than the average lunch sales during the rest of the week.Dinner sales, which generated at least $1,000 to $1,500 more a day than lunch sales, also remained steady during the week. Just like the lunch sales, the dinner sales peak on Friday and dipped down for the weekend.Excluding Wednesday and Thursday, the lunch and dinner sales from October 7-11 rose gradually until the end of the business week. Midweek, on Wednesday and Thursday, the sales were slightly lower than they were on Tuesday.According to the sales report, this restaurant has a steady lunch and dinner crowd. The most profitable day during the second week of October was Friday. Sunday, was the least profitable day, with the full days sales totaling/totalling less than the Friday dinner sales. These numbers are reflective of a restaurant that is located in a business/financial district where business hours are Monday through Friday.3. In June 1996, an experimental flu vaccine was trialled in a large country town on females only.Summarise the information by selecting and reporting the main features, and make comparisons where relevant.You should write at least 150 words.Give reasons for your answer and include any relevant examples from your own knowledge or experience. model answer:The diagrams show data for a flu epidemic which hit a large country town in 1996. Figure 1 gives the number of persons who died; Figure 2 shows the percentage breakdown of females who received a new flu vaccine; and Figure 3 gives the number of cases of flu before and during the epidemic.In Figure 1 it can be seen that the flu was responsible for the deaths of 2 females but no males in the period from March to May. However, from June to August, there were 4 female deaths and 1 male death.According to the pie chart in Figure 2, only those females most at risk were given the new flu vaccine; 28% did not take part in the trial. Of those females who took part, 35% were aged (over 65 years old); 24% were babies or children; and 13% were either hospitalised or receiving other medical attention.From Figure 3 it is clear that the new vaccine had a positive effect on the number of new cases of flu reported in females. There were just over 1000 cases reported in March, climbing rapidly to a peak of 3500 in June. Thereafter, the number of cases dropped slowly to about 2800 in August, before levelling off at 2500 for the rest of the year. For males, the figures were lower but showed a similar trend throughout the epidemic.(232 words)
