Answer:
Mrs. Langer makes 18 meatloaf muffins.
Explanation:
To find out how many meatloaf muffins Mrs. Langer makes, we need to determine the total amount of the meatloaf mix she has and then divide it by the amount of mix in each muffin cup.
First, let's find the total amount of the meatloaf mix:
Total mix = (Amount of ground beef) + (Amount of ground pork) + (Amount of ground tofu)
Total mix = 2 1/2 pounds + 1 1/4 pounds + 3/4 pound
To add these fractions and mixed numbers, we need to convert the mixed numbers to improper fractions:
2 1/2 = 5/2
1 1/4 = 5/4
Total mix = 5/2 pounds + 5/4 pounds + 3/4 pound
Total mix = (10/4) pounds + (5/4) pounds + (3/4) pounds
Total mix = 18/4 pounds
Convert this back to a mixed number:
Total mix = 4 1/2 pounds
Mrs. Langer puts 4 ounces of mix into each muffin cup. Since there are 16 ounces in a pound, this is equivalent to 1/4 pound.
Calculate the number of meatloaf muffins:
Number of muffins = Total mix / Amount per muffin
Number of muffins = (4 1/2 pounds) / (1/4 pound)
Dividing by a fraction is the same as multiplying by its reciprocal:
Number of muffins = (4 1/2 pounds) * (4/1)
Number of muffins = 18 muffins
Therefore, Mrs. Langer makes 18 meatloaf muffins.
