Question

At the theater, one section of seats has 8 rows with 12 Seats in each row. In the center of each of the first 3 rows are 4 broken seats that cannot be used. How many seats can be used in the section?

Answer 1

`84`

Explanation:

"8 rows with 12 seats in each row" means a total of `8\cdot12=96` seats in the theater.

"in the center of the first 3 rows are 4 broken seats that cannot be used" means broken seats `= 3\cdot4=12` total

So we have `96-12=84` usable seats.
