One costs $14,000 per batch, requires 3 tons of one major ingredient and 1 ton of the other, and yields 2 tons of output product. The second process costs $30,000 per batch, requires 2 and 7 tons of the ingredients, respectively, and yields 5 tons of product. The third process costs $11,000 per (b) TABLE 6.7 Optimization Output for Eli Orchid Exercise 6.2
