The cost per serving is approximately $4.45.
Steps to Solve
- Calculate the cost of ground beef
Jared buys 2 packages of lean ground beef for $9.88 each.
The total cost for the ground beef is:
$$ 2 \times 9.88 = 19.76 $$
- Calculate the cost of mozzarella cheese
Jared buys 3 packages of mozzarella cheese for $6.39 each.
The total cost for the mozzarella cheese is:
$$ 3 \times 6.39 = 19.17 $$
- Calculate the cost of noodles
Jared buys 2 boxes of noodles for $3.22 each.
The total cost for the noodles is:
$$ 2 \times 3.22 = 6.44 $$
- Calculate the cost of sauce
Jared buys 4 jars of sauce for $1.99 each.
The total cost for the sauce is:
$$ 4 \times 1.99 = 7.96 $$
- Sum all the ingredient costs
Now, add the costs of all ingredients to find the total cost:
$$ 19.76 + 19.17 + 6.44 + 7.96 = 53.33 $$
- Calculate the cost per serving
To find the cost per serving, divide the total cost by the number of servings (12):
$$ \text{Cost per serving} = \frac{53.33}{12} \approx 4.444 \approx 4.45 $$
The cost per serving is approximately $4.45.
More Information
This cost per serving helps to understand how much it would cost each person if the lasagna serves 12 people, making it helpful for budgeting and meal planning.
Tips
