15 = 80% * x

15 = 80/100 * x

15 = 8/10 * x

x = 15 * 10/8

x = 150/8

x = 18.75

Answer:

  • A: 24,500
  • B: 11,800
  • C: 12,700

Step-by-step explanation:

Since the number of A seats equals the total of the rest of the seats, it is half the seats in the stadium: 49000/2 = 24,500.

The revenue from those seats is, ...

  24,500×$30 = $735,000

so the revenue from B and C seats is ...

  $1,246,800 -735,000 = $511,800

__

We can let "b" represent the number of B seats. Then there are 24500-b seats in the C section and the revenue from those two sections is ...

  24b +18(24500-b) = 511800

  6b = 70,800 . . . . . . . . . . . . . . . subtract 441000, collect terms

  b = 70,800/6 = 11,800 . . . . . . . seats in B section

  24,500 -11,800 = 12,700 . . . . . seats in C section

There are 24500 seats in Section A, 11800 seats in Section B, and 12700 seats in Section C.
