Two months ago, lisa was honorably discharged from the air force where she spent four years training as an airplane mechanic. After discharge, she relocated to take a 40 hour per week apprentice mechanic job with a major airline company where she earns $18 an hour. Last month, her husband dave, who has worked the past two years as a registered nurse, found a nursing job with a local hospital making $625 per week. They just bought a new car and pay $400 each month on that loan and have no other monthly debts.
