You can put this solution on YOUR website!

let the total number of crowd be x
78 percent of x, or 0.78x, stood and cheered, 8800 were dejected
x=0.78x%2B8800
x-0.78x=8800
0.22x=8800
x=8800%2F0.22
x=40000-> total number
how many stood and cheered?
deduct 8800 from 40000
40000-8800=31200
or
find 78 percent of 40000
0.78x=0.78%2A40000=31200
so, 31200 stood and cheered
