Explanation:

Answer 2

A. 395.

B. 55.

Explanation:

A. We have been given that a survey found that 79% of the students agreed that fast food should be introduced.

To find the number of students, who want fast food served at the school cafeteria, we need to find 79% of 500.

`\text{Students who want fast food served at the school cafeteria}=(79)/(100)* 500`

`\text{Students who want fast food served at the school cafeteria}=0.79* 500`

`\text{Students who want fast food served at the school cafeteria}=395`

Therefore, 395 students of the 500 students want fast food served at the school cafeteria.

B. To find the students have no view on this matter, we will find 11% of 500 as 100%-(79%+10%)=11%.

`\text{Students who have no view on this matter}=(11)/(100)* 500`

`\text{Students who have no view on this matter}=0.11* 500`

`\text{Students who have no view on this matter}=55`

Therefore, 55 students have no view on this matter.
