To celebrate Cherry Hill’s 200th anniversary, 2000 people are invited to a formal dinner. If 12 people are seated at each table, how many tables will be needed?

3. 1. Read Visualize yourself in the problem as you re-read it. Facts
2000 people invited
Tables seat 12
Question
How many tables are needed?
