a. Marcus (age 68) and Alice (age 65 and blind) file a joint return. They furnish more than 50% of the support of a cousin, Ida, who lives with them. Ida (age 20) is a fulltime student and earns $3,500 during the year tutoring special needs children.

b. Penny (age 45) is single and maintains a household in which she and her nephew, Clint, live. Clint (age 18) earns $4,900 from doing yard work, but receives more than 50% of his support from Penny.

c. Trent (age 38) is single and lives alone. He provides more than 50% of the support of his parents (ages 69 and 70), who live in a nursing home.
