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

slamgirl [31]

There are 400 balcony seats in the concert hall.

<u>Step-by-step explanation</u>:

Step 1 :

The number of lower seats = 450 seats

Total seats = Lower seats + balcony seats

Step 2 :

Tickets sold = 170 tickets
Total tickets = x

Tickets sold = 1/5 of total tickets.

⇒ 170 = (1/5)x

⇒ x = 5 $\times$ 170

⇒ x = 850 tickets

∴ Total seats in the concert hall is 850.

Step 3 :

Total seats = 450 + balcony seats

850 - 450 = balcony seats

∴ balcony seats = 400
