Question 442401: Gather data on the amount of calcium and iron (in milligrams) found in one 10oz package of broccoli and in a 1/2 cup of frozen corn. The recommended daily values (in milligrams) of calcium and iron. After collecting the data, it should be clear that one 10oz package of broccoli and one 1/2 cup of frozen corn will not allow a person to achieve the minimum levels of calcium and iron for one day. To that end, you need to determin how much of each food item you need in order to reach those levels. Construct and solve a linear system of two equations that would make that determination.
