Question

An organization asked 500 students, selected at random from high schools across the United States, whether they want fast food served in school cafeterias. The survey found that 79% of the students agreed that fast food should be introduced, 10% disagreed, and the rest had no view on this matter.

Based on this data, 3951055550 of the 500 students want fast food served at the school cafeteria, and 3951055550 students have no view on this matter.

Answer 1

The results for 500 students were as follows:

Agree, fast food should be introduced 79%

Don't agree or disagree 11%

Disagree, fast food should not be introduced 10%

Answer 2

395 students agree

50 students disagree

55 had no view on this matter

Explanation:

The organization asked 500 students, 79% agreed on fast food being introduced in school. 10% disagreed and the rest had no view on this matter.

First, we are going to know the percent of students that had no view on this matter:

79% + 10% + x = 100%

where x is the students that had no view on this matter.

89% + x = 100%

x = 100% - 89%

x = 11%

So 11% of students had no view on this matter.

Now, we can see how many students voted in each category, to do this we have to multiply the total of students times the percent each option had.

Students that agreed that fast food should be introduced:

500*79% = 500 * 0.79 = 395 students

Students that disagreed:

500 * 10% = 500 * 0.10 = 50 students

Students that had no view on this matter:

500 * 11% = 500 * 0.11 = 55 students
