Question

There are 450 seats in the lower level of a concert hall with b balcony seats in the upper level. So far, 170 tickets have been sold, which is 1/5 if the total number of seats in the concert hall. How many tickets sold are balcony seats?

Answer 1

400 balcony seats

Explanation:

We know 170 tickets have been sold which is 1/5 of the total tickets

We have to find the total number of seats by doing 170x5

Now we know that there are 850 seats (170x5)

We have to subtract the lower seats from the total number of seats to find b (balcony seats)

850-450 = 400

Therefore, b is equal to 400 balcony seats
