Mrs. Linda has 17.16 cups of brownie mix. If each brownie uses 0.33 cups of mix, how many brownies can Mrs. Linda make?
52
53
54
22
The correct answer and explanation is:
To solve this, divide the total amount of brownie mix by the amount needed for one brownie.
The formula to use is: Number of brownies=Total amount of mixAmount per brownie\text{Number of brownies} = \frac{\text{Total amount of mix}}{\text{Amount per brownie}}
Given:
- Total amount of brownie mix = 17.16 cups
- Amount of mix for each brownie = 0.33 cups
Now, divide 17.16 by 0.33: 17.160.33=52\frac{17.16}{0.33} = 52
So, Mrs. Linda can make 52 brownies.
Explanation:
The division method is appropriate here because we are distributing the total amount of mix (17.16 cups) equally among each brownie (which requires 0.33 cups). Each division represents the amount of brownies she can make from each portion of mix. This simple division yields 52 as the number of brownies she can produce.
In real-world terms, this calculation reflects that Mrs. Linda has enough mix to prepare 52 individual brownies, each using 0.33 cups. This scenario can be useful for determining how many servings or individual portions can be created from a bulk amount of ingredients. In this case, 52 brownies is the correct answer, and it follows directly from dividing the total cups of mix by the portion size for each brownie.
