In the lunch room at your school, 5 people can sit at one table. If you put two tables together, 8 people can sit. If you put three tables together, 11 people can sit. How many people can sit if you put 20 tables together?

Respuesta :

5 people at the table base, increased by 3 with each additional table. 19 x 3 = 57 + 5 (base table capacity) = 62 people.
