How much does each have Alex has twice as much money as Jennifer. Jennifer has 6 less than Shannon. Together they have 54.?

Let Jennifer's amount be ( J ) and Shannon's amount be ( S ). Since Alex has twice as much as Jennifer, we have ( A = 2J ). Given that Jennifer has 6 less than Shannon, we can express it as ( J = S - 6 ). The total amount they have together is ( A + J + S = 54 ).

Substituting ( A ) and ( J ) gives us ( 2J + J + (J + 6) = 54 ), which simplifies to ( 4J + 6 = 54 ). Solving for ( J ), we find ( J = 12 ), ( S = 18 ), and ( A = 24 ). Therefore, Alex has $24.
