Mrs. Valdez wanted to determine the number of people, p, she could safely take in her car to the fun run. She determined that p < 5.

The condition p < 5 means the number of people must be less than 5. Since people are counted in whole numbers and the number cannot be negative, 2 people is a valid choice. The choice of 3.5 is not a whole number of people, and 5 is not less than 5.
