A waffle recipe calls for different amounts of mix, depending on the number of servings. For 4 servings, Jordan needs 3 cups of mix and for 12 servings; she needs 9 cups of mix. This shows a direct variation between the number of servings (x) and the amount of mix (y). Using the formula y =kx, solve the formula for k and then give the value of k.
