Sarah's comprehensive major medical health insurance plan at work has a deductible of $750. The policy pays 85 percent of any amount above the deductible. While on a hiking trip, she contracted a rare bacterial disease. Her medical costs for treatment, including medicines, tests, and a six-day hospital stay, totaled $8,893. A friend told her that she would have paid less if she had a policy with a stop-loss feature that capped her out-of-pocket expenses at $3,000. Was her friend correct? Show your computations. Then determine which policy would have cost Sarah less and by how much.
