Question

the two - way table given shows the results from the lunch orders from an upperclassman barbecue.

	11th graders	12th graders
hotdog	55	25
chicken wings	24	26

a segmented bar chart was created showing the lunch preference by grade. what percent would the bar for 11th graders show for preferring chicken wings?
options: 15%, 24%, 45%, 66%

Explanation:

Step1: Calculate total 11th graders

Sum the number of 11th graders for each food: \( 81 + 55 + 24 \).
\( 81 + 55 = 136 \), \( 136 + 24 = 160 \).

Step2: Calculate percentage for chicken wings

Divide 11th graders who prefer chicken wings (24) by total 11th graders (160), then multiply by 100.
\( \frac{24}{160} \times 100 = 0.15 \times 100 = 15\% \).

Answer:

15%
