Math in Your Life: Between the Numbers.
As we have mentioned, textbook problems are often simpler than real-life problems. Describe at least three aspects of Khalid’s diet in Example 9 that might be relevant that we have not included. We are not asking for a mathematical discussion here, just an indication of what might be included in a more comprehensive description of the problem.
Example 9 Using Inequalities to Represent Nutritional Requirements.
Khalid is a marathon runner who is interested in the amount of protein and calcium in his diet. Two of his favorite foods are fried shrimp and broccoli. A serving of fried shrimp contains approximately 15 g of protein and 60 mg of calcium. A spear of broccoli contains 5 g of protein and 80 mg of calcium. Assume that, as part of his diet, he wants to get at least 60 g of protein and 600 mg of calcium from fried shrimp and broccoli. Express this pair of conditions as a system of inequalities and graph its solution set.
