A cafeteria is trying to scale a small pancake recipe up in order to feed a group of tourists. The recipe feeds 6 people and the recipe is trying to feed 75. The recipe calls for 4 cups of flour, 1 1/2 cups of milk, and 1/2 cups of sugar. If one 10 pound bag of flour contains 16 cups of flour, how many pounds of flour will be needed for this recipe?
