drink preferences
lemonade
root beer
other
number of students
what percent of students preferred lemonade or root beer?
write your answer using a percent sign (%)

Explanation:

Step1: Find the number of students who preferred lemonade, root - beer and others

From the bar graph:
Number of students who preferred lemonade \(= 150\)
Number of students who preferred root - beer \(= 850\)
Number of students who preferred others \(= 700\)

Step2: Calculate the total number of students

Total number of students \(=150 + 850+700=1700\)

Step3: Calculate the number of students who preferred lemonade or root - beer

Number of students who preferred lemonade or root - beer \(=150 + 850 = 1000\)

Step4: Calculate the percentage

The formula for percentage is \(\text{Percentage}=\frac{\text{Part}}{\text{Whole}}\times100\)
Here, the part is the number of students who preferred lemonade or root - beer (\(n = 1000\)), and the whole is the total number of students (\(N=1700\))
\(\text{Percentage}=\frac{1000}{1700}\times100=\frac{100000}{1700}\approx58.82\%\)

Answer:

\(58.82\%\)
