Answer:
- A: 27,500
- B: 14,700
- C: 12,800
Step-by-step explanation:
Section A holds half the seats in the stadium, so 27,500 seats.
Revenue from a sold-out section A will be ...
$35×$27500 = $962,500
so the combined revenue from B and C seats is ...
$1,448,500 -962,500 = $486,000
If we let "b" represent the number of section B seats, then the number of section C seats is (27,500 -b) and the revenue from sold-out sections B and C will be ...
20b +15(27500 -b) = 486000
5b = 73,500 . . . . . . . . subtract 412,500
b = 14,700 . . . . . . . . . . divide by 5; number of Section B seats
27,500-b = 12,800 . . . number of Section C seats
There are 27,500 Section A seats, 14,700 Section B seats, and 12,800 Section C seats.
