Vicky's comprehensive major medical health insurance plan at work has a deductible of $650. The policy pays 90% 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 $9860. 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 $3400. The policy with the stop-loss feature has the same deductible and coinsurance requirement as Vicky's current policy. (Round your intermediate calculations and final answer to 2 decimal places)
