adults=24

children=36

Step-by-step explanation:

x+y=60

400x+250y=18600

x=60-y

400(60-y)+250y=18600

y=36.

solve this expression then u will get the answer for y.

x+36=60

x=24.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
