    Dale: $360

    Tammy: $120

    Brian:$127

    Tammy, Brian and Dale have $127 altogether.

    Dale's rule: 3 * what Tammy has (3y y=Tammy's money). 120 * 3=$360

    Tammy's Rule: $7 less than Brian (b-7 b = Brian's money). 127 - 7 = $120

    Brian has $127 in his wallet because there is no description of what changes in his money.
