【答案解析】Quarter-to-quarter sales increased throughout the year in every division. However, sales increase in the East and North are relatively modest, never over 10% percent in each quarter. By contrast, fourth quarter sales in the West and South jumped dramatically by over 200 percent. All four divisions exceeded Their quotas, although the percentages of their excesses vary from one another. Again, sales in the West and South exceeded their quota by greater percentages than in the North and East. In conclusion, it appears that we could probably establish next year’s quotas at a level slightly above this year's sales. The increases of sales in the South and West seem to justify our decision to expand operations in both areas. While opportunities are more limited in the East and North, it may bo cost-effective to try a limited expansion there.
