Can you PLEASE help me with these Tax questions?

Using 2017 tax law, answer this question about the following scenario. Numbers in parentheses indicate age. Each taxpayer has only the income stated. Unless otherwise stated, each prospective dependent is an unmarried U.S. citizen who does not provide more than half of their own support. In no case will more than one taxpayer attempt to claim the same qualifying child as a dependent. No one other than the persons listed lived in the home.
