A Broadway theater has 400 ​seats, divided into​ orchestra, main, and balcony seating. Orchestra seats sell for $ 80 comma main
Tomtit [17]

Answer:

80 orchestra seats

180 main seats

140 balcony seats

Step-by-step explanation:

Total number of seats = 400

Orchestra seats sell for $80

Main seats sell for $65

Balcony seats sell for $40

If all the seats are sold, gross revenue = $23,700

If all the main seats and balcony seats are sold but only half of the orchestra seats are sold, the gross revenue = $20,500

Let x = Orchestra seats

Let y = main seats

Let z = balcony seats

x+y+z= 400............. (1)

Orchestra seats sell for $80, Main seats sell for $65 and bslcony seats sell for $40. The gross revenue if all the seats are sold = $23,700

80x + 65y + 40z = 23,700 ........(2)

If half of the orchestra seats are sold while all main and balcony seats are sold, we have

80(0.5x) + 65y+ 40z = 20,500

40x + 65y + 40z = 20,500 .....(3)

we have the simultaneous equations

x+y+z= 400............. (1)

80x + 65y + 40z = 23,700 ........(2)

40x + 65y + 40z = 20,500 .....(3)

Using elimination method to solve equation 2 and 3, we subtract equation 3 from 2

40x = 3200

x = 3200/40

x = 80 orchestra seats

Put x= 80 into equation 1 and 2

From equation 1,

x +y+z = 400

y + z = 400 - x

y+z = 400 -80

y+z = 320 .........(4)

From equation 2,

80x + 65y + 40z = 23,700

80(80) + 65y +40z = 23,700

6400 + 65y + 40z = 23,700

65y+40z = 23,700 - 6400

65y + 40z = 17,300 .........(5)

Multiply equation (4) by 40 and equation (5) by 1

So we have

40y + 40z = 12,800

65y + 40x = 17,300

subtract both equations from each other. we have

-25y = -4500

y = -4500/-25

y = 180 main seats

Put x = 80 and y= 180 into equation (1)

80+180+z = 400

260 + z = 400

z = 400-260

z = 140 balcony seats
