Question

There are 15 students in a class. 9 of them play basketball, and 11 of them play soccer. How many students in the class play both soccer and basketball

Answer 1

We will see that the number of students that play both sports is given by the inequality:

5 ≤ x ≤ 9

How to find the number of students that play both sports?

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 number of students 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
