Question

The school cafeteria staff conducted a survey to see which type of pizza was the most popular among the students. The graph shows the results of the survey. How many students responded to the survey?

Answer 1

ANSWER

The number of students who responded to the survey was
$110$


EXPLANATION


We need to read the frequency from the graph and add them. This will give us the number of students who took the survey.



The height of the bars gives the frequency of each category.


From the graph we can find the number of students who liked each type of pizza.

$cheese = 45 \: \: students$


$sausage = 35 \: students$


$pepperoni = 30 \: \: students$

Therefore the number of students who responded to the survey
$= 45 + 35 + 30 = 110 \: \: \: students.$
