We will see that the number of students that play both sports is given by the inequality:
5 ≤ x ≤ 9
<h3>
How to find the number of students that play both sports?</h3>
We do know that in the class, there are 15 students.
Such that:
- 9 of them play basketball.
- 11 of them play soccer.
If you add these numbers, you get:
9 + 11 = 20
This gives more than the number of students that we have, to get the minimum <em>number of students</em> that play both sports we subtract the number of students:
20 - 15 = 5
5 students play both sports, but this is the minimum number.
There is also the case where out of the 11 students that play soccer, there are 9 that play basketball (so 9 students play both sports) and 4 students don't play any sport.
So the number of students that play both sports is given by the inequality:
5 ≤ x ≤ 9
