You don't know. It depends on whether Mary earned more or less than $8. If Mary earned $4, then Jack earned $8 and Jill earned $12, so Jill made the most. But if Mary earned $8, then Jack earned $16 and Jill also earned $16, so there was a tie. If Mary earned $12, then Jack earned $24 and Jill earned $20, so Jack made the most.

Not enough information. If Mary makes less than $8, then Jill makes the most. If Mary makes more than $8, then Jack makes the most. If Mary makes $8, then Jack and Jill both make $16.
