An individual needs a daily supplement of at least 500 units of vitamin c and 200 units of vitamin e and agrees to obtain this supplement by eating two foods, i and ii. each ounce of food i contains 40 units of vitamin c and 10 units of vitamin e, while each ounce of food ii contains 20 units of vitamin c and 20 units of vitamin e. the total supplement of these foods must be at most 30 ounces. unfortunately, food i contains 30 units of cholesterol per ounce and food ii contains 20 units of cholesterol per ounce. find the appropriate amounts of the two food supplements so that the cholesterol is minimized. find the minimum amount of cholesterol. (steps: (1) identify variables, constraints, objective equation (2) graph feasible region (3) find corners (4) solve using method of corners)
