In a traditional pound cake recipe, you have the following ingredients:
- 1 pound of sugar
- 1 pound of butter
- 1 pound of eggs
- 1 pound of flour
Total weight of the cake = 1 pound (sugar) + 1 pound (butter) + 1 pound (eggs) + 1 pound (flour) = 4 pounds.
To find the percentage of the cake that is flour, you can use the formula:
\[ \text{Percentage of flour} = \left( \frac{\text{Weight of flour}}{\text{Total weight of cake}} \right) \times 100 \]
Plugging in the numbers:
\[ \text{Percentage of flour} = \left( \frac{1 \text{ pound}}{4 \text{ pounds}} \right) \times 100 = 25% \]
So, the correct response is 25%.
