Adult ticket costs= $46

Children ticket costs= $104

Let x represent the price of adult tickets

Let y represent the price of children tickets

x + y= 150.......equation 1

8x + 3y= 970........equation 2

From equation 1

x= 150 - y

substitute 150-y for x in equation 2

8(150-y) + 3y= 970

1200- 8y + 3y= 970

-8y + 3y= 970-1200

-5y= -230

y= 230/5

y= 46

From equation 1

x + y= 150

x + 46= 150

x= 150 - 46

x= 104

Hence the cost of children tickets is $104 and the cost of adult tickets is $46
