N=28
cross multiply 7 and 36
cross multiply 9 and n
7x36=252
9xN=9n
9n=252
—- ——
9 9
n=28
26 = orchestra
11 + 13 = 24 = choir
26 x 2 = 52 = band
52 + 24 + 26 = 102 people in all the following on top.

Step-by-step explanation:
3x - 5x - 4 - x^2 + 12x - 17x^2 - 16
= -2x - 20 - 18x^2 + 12x
= 10x - 20 - 18x^2
