Answer 2

Answer:

Number of Adults in the Theater

To find the number of adults in the theater, we need to compare the number of children to the number of adults. We are given that there are 10 children per row and that this is three times more than the number of adults. Let's assume the number of adults is "x". Therefore, the number of children would be 3 times "x", which is 3x. We can set up the equation:

3x = 10x10

Solving this equation, we find that x = 10. Therefore, there are 10 adults in the theater.

Total Number of Seats in the Theater

To find the total number of seats in the theater, we need to calculate the number of seats in each row and then multiply it by the number of rows. We are given that there are 15 rows with 8 seats each and 10 rows with 10 seats each. Let's calculate the total number of seats:

Number of seats in rows with 8 seats: 15 rows * 8 seats/row = 120 seats Number of seats in rows with 10 seats: 10 rows * 10 seats/row = 100 seats

Total number of seats in the theater: 120 seats + 100 seats = 220 seats.

Therefore, there are 220 seats in the theater.
