Alexander, who weighs 150lb, decides to climb Mt. Krumpett, which is 5250 m high. For his food supply, he decides to take nutrition bars. The labels on the bars states that each 100-g bar contains 10 g of fat, 40 g of protein, and 50 g of carbohydrates. One gram of fat contain 9 Calories, whereas each gram of protein and cabohydrates contain 4 Calories. Alexander wants to know excatly how many bars to pack for the journey. To provide a margin of safety, he assumes that he will need as much energy for the return trip as the uphill climb. How many bars should Alexander pack
