Question

Explanation:

Step1: Determine number of Shasta - preferring classmates

From the bar - chart, the number of classmates who prefer Shasta is 10.

Step2: Calculate the percentage

The formula for percentage is $\frac{\text{Number of Shasta - preferring classmates}}{\text{Total number of classmates}}\times100\%$. The total number of classmates surveyed is 25. So the percentage is $\frac{10}{25}\times100\%$.
$\frac{10}{25}\times100\% = 0.4\times100\%=40.0\%$

Answer:

40.0
