There are 40 tables in a library, with 30% of them seating 4 people. The tables remaining only seat 2 people. How many seats are there in the library?

Question

Trying to find the number of seats in the library

Answer 1

30%(40)= 12; therefore, 12 tables seat 4 each, a total of 4(12) = 48 people.

The remaining tables, 40 - 12 = 28 seat 2 each, a total of 2(28) = 56 people.

 

The library seats a total of 48 + 56 = 104 people.
