Answer:
Either 48 or 24 you choose based on my explanation.
Explanation:
If there are 12 people and each table holds 4 people then it is an easy multiplication problem of 12 x 4 = 48.
But since they are lined up end to end you can only fit two people on either side of the table. This would amount to 24 people. 12 x 2 = 24
