You can put this solution on YOUR website! A diabetic patient wishes to prepare a meal consisting of roasted chicken breast, mashed potatoes, and peas.
A 3-oz. serving of roasted skinless chicken breast contains 140 Cal, 27 g of protein, and 64 mg of sodium. A one-cup serving of mashed potatoes contains 160 Cal, 4 g of protein and 636 mg of sodium, and a one-cup serving of peas contains 125 Cal, 8 g of protein, and 139 mg of sodium. How many servings of each should be used if the meal is to contain 415 Cal, 50.5 g of protein, and 553 mg of sodium?
--------------------------
140c + 160m + 125p = 415 calories
27c + 4m + 8p = 50.5 protein
64c + 636m + 139p = 553 sodium
--------------------------
Use any method you know to solve the system to get::
c = 1.5 servings of chicken breast
m = 0.5 servings of mashed potatoes
p = 1.0 servings of peas
