Libby, age 32, can do it all. She works 30 hours a week at her daytime job as a technical writer for the county. She also freelances as an editor and ghost writer. Her gross pay from her county job is $30,000 per year. Out of this she pays $2,000 for health insurance premiums (insurance purchased through her employer's cafeteria plan), contributes $3,000 to her health savings account (also through the cafeteria plan), and contributes $1,500 to her employer's 457(b) plan. The county also pays for a group term life insurance policy for Libby. The value of the policy is 5 times Libby's base pay. Libby's freelance work last year generated net income of $20,000. Libby recently copy-edited a local photographer's website and in exchange the photographer took free pictures of Libby and her family. The pictures and photo shoot session would normally sell for $150. Libby would typically charge $200 for her copyediting services. Jake and his 3 year-old daughter, Jane, live with Libby. Jane is not Libby's daughter, but she thinks of her as her own. Jake loves to surf and teaches surfing lessons when he is not watching his daughter Jane. Jake makes cash income from his surf lessons but has to pay a sitter for Jane so he can teach them. He made $5,000 (after expenses) last year teaching surf lessons.
