    94 Child tickets were sold.

    Step-by-step explanation:

    Let x represent child tickets

    Let y represent adult tickets

    Cost Equation: 5.70x + 9.75y = 1306.10

    Quantity Equation: x + y = 173

    Multiply the Quantity Equation by - 5.70

    5.70x + 9.75y = 1306.10

    -5.70x - 5.70y = - 986.10

    4.05y = 320.00

    :4.05 : 4.05

    y = 79

    x + y = 173

    x + 79 = 173

    x = 94
