A recipe for lemonade punch calls for 6 cups of lemonade for every 24 cups of punch. Which equation can be used to find [tex]x[/tex], the percent of lemonade in the recipe?

A. [tex]\frac{6}{24} = \frac{x}{100}[/tex]

B. [tex]\frac{24}{30} = \frac{x}{100}[/tex]

C. [tex]\frac{24}{6} = \frac{x}{100}[/tex]

D. [tex]\frac{6}{30} = \frac{x}{100}[/tex]

Answer :

To find the percent of lemonade in the punch recipe, we can use the concept of proportions. Here's how you can solve it step by step:

1. Understand the Ratio: The recipe states that there are 6 cups of lemonade for every 24 cups of punch. This ratio can be represented as:

[tex]\[
\frac{\text{cups of lemonade}}{\text{cups of punch}} = \frac{6}{24}
\][/tex]

2. Convert Ratio to Percentage: To find out what percentage of the punch is lemonade, you need to express this ratio as a percentage. The percentage formula for a part-to-whole relationship is:

[tex]\[
\frac{\text{part}}{\text{whole}} \times 100 = \text{percent}
\][/tex]

Here, the "part" is the cups of lemonade (6) and the "whole" is the total cups of punch (24).

3. Set Up the Equation: Set up the equation based on the above formula to solve for [tex]\( x \)[/tex], the percent of lemonade in the punch:

[tex]\[
\frac{6}{24} = \frac{x}{100}
\][/tex]

4. Solve for [tex]\( x \)[/tex]: Solve this proportion to find [tex]\( x \)[/tex].

[tex]\[
6 \times 100 = 24 \times x
\][/tex]

[tex]\[
600 = 24x
\][/tex]

[tex]\[
x = \frac{600}{24} = 25
\][/tex]

5. Conclusion: Therefore, the percentage of lemonade in the punch is 25%, and the equation that represents this is:

A. [tex]\(\frac{6}{24} = \frac{x}{100}\)[/tex]

This logical and proportional reasoning guides us to the conclusion that the correct answer is option A.
