Question

A survey was conducted with S students 30% of those surveys said that they have traveled out of the country. Of the students who have never been out of the country 40 students had eventually travel to another Country write an algebraic expression that represents the students who never want to travel to another country

Answer 1

The students who never want to travel to another country Y= 7S/10 -40

Explanation:

Let's assume the number of students who have never been to another country be Y.

Then as per question 30% percent students have traveled out of the country.

Therefore 70% students out of S have never traveled to another country.

Equation becomes like Y= S×70÷100

Y = 7S/10

Now it is stated that 40 students of the students who have never been out of the country had eventually travel to another country.

Therefore the equation will be Y = 7S/10-40
