    Answer:$20

    Step-by-step explanation:

    The total money paid

    $105 + $125 + $175 = $405

    If they are to share the cost equally, then each are to pay $405 : 3 = $135 each

    Since tom paid $105, He need to give out $30 more to make it $135, so he will give sam $30

    Since Dorothy initially Paid $125, he will need to give out $10 to make his total pay $135, so he gave sam $10

    Therefore $t = 30 and $d=10

    $t - $d = $30 - $10 = $20
