No this is not the answer

Answer:

Child $13 and Adult $14

Step-by-Step

x=cost of child tix

y=cost of adult tix

first day: 5y+6x=148

2nd day: 7y+7x=189

series of equations so solve for one variable

7y=189-7x

y=27-x

then plug into other equation

5(27-x)+6x=148

135-5x+6x=148

x=148-135

x=13

then plug into y equation

y=27-13

y=14
