The additional number of people is [4, 13]

How to determine the number of people?

Brittany and four of her friends are five people.

So, we have:

n = 5

The conditions are given as

  • At least = 9
  • At most = 18

Let the additional number of people be x

So, we have the following inequalities

x + 5 ≥ 9 and x + 5 ≤ 18

Subtract 5 from both sides

x ≥ 4 and x ≤ 13

Express as interval notation

[4, 13]

Hence, the additional number of people is [4, 13]
