This has to do with linear programming.

You are thinking of combining Xtend and RecoverMode to provide you with the required nutrients. How many servings of each should you combine to obtain a week's supply that meets your trainer's specifications at the least cost? Let x = number of servings of Xtend, let y = number of servings of RecoverMode, and let c = cost (in dollars). Determine the objective and the constraints needed to solve the problem.
