There are 40 tables in a library, with 30% of them seating 44 people. The tables remaining only seat 22 people. How many seats are there in the library?

104

100 To find out how many seats are there in the library, we need to calculate the total number of seats for each type of table and then add them together.

First, let's calculate the number of tables that can seat 44 people. We know that 30% of the 40 tables can seat 44 people, so we can find this value by multiplying 40 by 30% (or 0.3):

Number of tables seating 44 people = 40 * 0.3 = 12 tables

Since each table can seat 44 people, the total number of seats for these tables would be:

Total seats for tables seating 44 people = Number of tables seating 44 people * Seats per table = 12 * 44 = 528 seats

Next, let's calculate the number of tables that can seat 22 people. These would be the remaining tables after excluding the tables seating 44 people, which is equal to the total number of tables (40) minus the number of tables seating 44 people (12):

Number of tables seating 22 people = Total number of tables - Number of tables seating 44 people = 40 - 12 = 28 tables

Since each table can seat 22 people, the total number of seats for these tables would be:

Total seats for tables seating 22 people = Number of tables seating 22 people * Seats per table = 28 * 22 = 616 seats

Finally, we can find the total number of seats in the library by adding the seats from both types of tables:

Total number of seats in the library = Total seats for tables seating 44 people + Total seats for tables seating 22 people = 528 + 616 = 1,144 seats

Therefore, there are 1,144 seats in the library.
