Question

Lindsay needs to interview a minimum of 15 people for a project in her

health class. So far she has interviewed 6 people. Write and solve an
inequality to find p, the possible number of people she still needs to
interview to complete the project.

Answer 1

The required inequality is p≥9

Explanation:

Given condition:

Lindsay needs to interview a minimum of 15 people.

Lindsay completed interviewing 6 people.

To Find:

The possible number of people she still needs to interview to complete her project.

Solution:

Let p be the number of people needed to complete the project.

To complete the project Lindsay needs to interview minimum 15 people.

i.e.p≥ 15

But she has already interviewed 6 people. so, (15-6) = 9

i.e p+6≥15

or, p+6≥15

∴ p≥9

Hence the inequality that shows the people she still needs to interview to complete the project is p≥9.
