    Answer:

    Hence the cost of adult tickets is $8

    and the cost of child ticket is $4

    Step-by-step explanation:

    Given data

    Let the cost per adult be x

    and the cost per child be y

    So

    3x+2y= 32————1

    8x+5y= 84————2

    Now solving 1 and 2 simultaneously, we have

    3x+2y= 32————1X  5

    8x+5y= 84————2 X 2

     15x+ 10y= 160

     16x+ 10y= 168

    -x+0)=-8

    -x= -8

    x= 8

    Put x= 8 in 1 to find y

    3*8+2y= 32

    24+2y= 32

    2y= 32-24

    2y= 8

    y= 4
