let consider
No.of adult = x
no.of children = y
no. of guest is 201
x + y = 201
x = 201 -y
charity event charged $8.50 per child and $14 per
adult.
adult.
14x + 8.50y = 2550
14(201 -y) +8.50 y=2550 ...............by subsituting x =201-y
2814 -14y + 8.50y =2550
-5.5 y = -264
y= 48
x = 201 -y=201-48 = 153
No.of adult = x =153
no.of children = y =48
no.of children = y =48
