Box seats sell for 10 dollars, lower-deck seats sell for 8 dollars, and upper-deck seats sell for 5 dollars. If all the seats are sold, the total revenue for a game is 70000 dollars. The stadium has 4 times as many upper* deckseats as box seats. How many lower-deck seats are in the stadium?

Number of box seats = 1000

Number of lower deck seats = 5000

Number of upper deck seats = 4000

Step-by-step explanation:

Let number of box seats =

Let number of lower deck seats =

Let number of upper deck seats =

As per question statement:

...... (1)

Cost for box seat = $10

Cost for box seats = 10

Cost for lower deck seat = $8

Cost for lower deck seats = 8

Cost for lower deck seat = $5

Cost for lower deck seats = 5

As per question statement:

..... (2)

..... (3)

Putting value of in (1) and (2):

....... (4)

8 (4) - (5):

10000

By (3):

Now, by equation (1):

= 5000

Number of box seats = 1000

Number of lower deck seats = 5000

Number of upper deck seats = 4000
