Diesel Cost and Market Areas Consider Figure 23 , which shows the market areas of sugar-beet processing plants. Suppose that an increase in the price of diesel fuel doubles the cost of hauling sugar beets from farms to processing plants. Modify Figure 23 to show the effects of higher transport costs.
