Algebra Difficulty 1.2 Junior Find the answer Canada

A grade 8 class surveyed its students to see how they get to
school each day. The data collected is in the chart shown.

How student gets to school	Number of students
Walk	$10$
Bike	$5$
Bus	$9$
Car	$6$

The percentage of the students that get to school by car is

Pick one

Solution

The total number of students surveyed was $10+5+9+6=30$ .

Of the $30$ students surveyed, $6$ students arrive by car.

Thus, the percentage of students that get to school by car is $\dfrac{6}{30}\times100\%=\dfrac{1}{5}\times100\%=20\%$ .
