Could someone assist me with these taxes problems:

1. Aidan is unmarried. His mother, for whom he can claim an exemption, lived in an apartment by herself. She died on September 2. The cost of the upkeep of her apartment for the year until her death was $6,000. Aidan and his brother both paid support and their mother had no income. Aidan would qualify to file as head of household if he paid what amount of his mothers support?

a) $1,000

b) $1,500

c)$2,000

d) $4,000

2. Charlie and Marianne are both over 65. Their adjusted gross income is $100,000. During the year their 35-year-old single son, Lenny, lived with them while attending college and earned $4,500. Charlies mother, Elizabeth, lived with them until June 1 when she was placed in a nursing home for an indefinite period of time to receive medical care. Elizabeth received no income and was supported solely by Charlie and Marianne. Determine the number of exemptions Charlie and Marianne can claim on their joint return.

a) 1

b) 2

c) 3

d) 4

3. Patricia is a 39-year-old single California resident and has a 12-year-old son named Luke. He lives with her during the 9-month school year in California and spends the 3 summer months with his father in Idaho. She provides approximately 75% of his support. Which of the following regarding Lukes dependency status is correct?

1) Patricia must alternate claiming Luke as a dependent with his father

2) Based on Lukes relationship with Patricia, his age, and that he lives with her for more than half the year, she can claim him as a dependent

3) Based on the fact Luke lives with Patricia for only 9 months a year, she cannot claim him as a dependent

4) Since Patricia only provides 75% of Lukes support, she cannot claim him as a dependent
