Answer:
Adults =1500 and student= 2500
Step-by-step explanation:
Step one:
GIven data
let Adults be x and student be y in numbers
so
5x+3y=15000------------1
x+y=4000---------------------2
from 1
x=4000-y, put this in 2, we have
5(4000-y)+3y=15000
20000-5y+3y=15000
-2y=15000-20000
-2y= -5000
2y=5000
divide both sides by 2
y= 2500
put y= 2500 in 2
x+2500= 4000
x= 4000-2500
x=1500
