A credit union has seven branches; each branch has three departments, and each department has three employees. How many total people does the credit union employ?

63 people

Step-by-step explanation:

Seven branches, each with three departments. Each department with 3 people

7 (branches) times 3 (departments (departments per branch)) equals 21 (departments in total)

21 (departments in total) time 3 (people (people per department)) equals 63 (people in total)
