Final answer:
For 15 servings of Lasagna, 40 ounces of Italian Sausage would be needed. With 24 ounces of Italian Sausage, you can make 9 servings of Lasagna. This is determined through setting up and solving proportional relationships based on the original recipe.
Step-by-step explanation:
Proportional Relationships in Recipes
To find out how much Italian Sausage is needed for 15 servings of Lasagna, we use a proportional relationship based on the original recipe. If 16 ounces of sausage is used for 6 servings, then we can find the amount for 15 servings by setting up a proportion:
16 ounces / 6 servings = x ounces / 15 servings
Cross multiplying gives:
(16 ounces) × (15 servings) = x ounces × (6 servings)
Therefore:
(16 × 15) / 6 = x
(240) / 6 = x
x = 40 ounces
So, you would need 40 ounces of Italian Sausage for 15 servings of Lasagna.
To determine how many servings can be made with 24 ounces of Italian Sausage, we set up another proportion:
16 ounces / 6 servings = 24 ounces / y servings
Cross multiplying gives:
(16) × (y) = (24) × (6)
Therefore:
(144) / 16 = y
y = 9 servings
You can make 9 servings of Lasagna with 24 ounces of Italian Sausage.
