Diana and her family are eligible for dental benefits under her employer's group dental plan. The plan provides for orthodontic coverage with a 50% coinsurance up to a lifetime maximum benefit of $2,000 per eligible insured. There is no deductible. Diana, her husband and each of their children are considered insured individuals for orthodontic benefits. Diana's son Tim began orthodontic work in 2007 with total orthodontic expenses of $3,000 in 2007 and $3,000 in 2008. Her son Tom began orthodontic work in 2008, and incurred total orthodontic expenses of $3,000 that year. Assuming Diana claims eligible expenses on a calendar year basis, how much was she reimbursed in 2008?
