Answer:
22 Tables Were Used
Explanation:
Since each table can fit 10 people, we need to divide 214 by 10 to find out how much tables were used.
214/10=21 remainder 4.
The problem says that every table was full except for the last one. So, there can’t be 4 remainder people in a 10 person table. Therefore we should add another table which makes 22.
Answer: 22 tables were used.
