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

Let 'S' represent the number of seats in the library.

30% of 40 tables is 0.30 x 40 = 12 tables.

The number of remaining tables is 40 - 12 = 28 tables.

0.30 x 40 x 4 + 28 x 22 = S

S = 664 seats

There are 664 seats in the library.

there are 104 seats because when you think about it it will b e between 100 and 200 and the nearest estimate to the answer is 104

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2
