    A: $6

    If hat price is x, the goat price is y,times is n.(at least 3 times).
    Total=10n+x, total=y.y, y.y=10n+x(0=3).
    y=√10n+x
    so 10n+x should be 36, 49, 64,81, 100, 121, 144, 169, 196, 225, 256, 576......

    The N should be odd number, so it will be: 36, 196, 256, 576.....

    So the price should be $6.00.

    Finally,the elder one got $10 but the younger one got less than $10.

    it means the amount is 10 above and 20 below, meanwhile is a square number, only 16.

    the answer is 2 dollars.

      the elder get 10, the younger get 6, the elder should give the younger 2 to balance the gap.

    If hat price is x, the goat price is y,times is n.(at least 3 times).
    Total=10n+x, total=y.y, y.y=10n+x (n>=3,0<10).
    y=√10n+x
    so 10n+x should be 36, 49, 64,81, 100, 121, 144, 169, 196, 225, 256, 576......
