Answer 2

30 students not take bus to school .

Explanation:

As given

Bill is in a class of 15 boys and 35 girls.

Total number of students in the class = Number of boys + Number of girls

= 15 + 35

= 50

As given

40% of the students in the class take the bus to school.

40% is written in the decimal form.

`= (40)/(100)`

= 0.40

Number of students take bus to school = 0.40 × Total students in class.

= 0.40 × 50

= 20

Thus

Students not take bus to school = Total students - Number of students take bus to school

= 50 - 20

= 30

Therefore 30 students not take bus to school .
