vegetarian	24	30

a segmented bar chart was created showing the lunch preference by grades. what percent would the bar for 11th and 12th graders show for preferring a ham sandwich?
74%
16.4%
29.6%
53.6%

Explanation:

Step1: Calculate total for 11th-12th graders

Sum the number of 11th - 12th graders who ordered each sandwich: \(146 + 74 + 30 = 250\).

Step2: Calculate percentage for ham

The number of 11th - 12th graders who ordered ham is 74. The percentage is \(\frac{74}{250} \times 100 = 29.6\%\).

Answer:

29.6% (corresponding to the option with 29.6%)
