Suppose Sherisa has a health insurance policy that has a $1,000 deductible for hospital stays. Sherisa recently got very sick and had to be hospitalized for five days. In addition to the deductible, Sherisa's health insurer requires 20% coinsurance on amounts above the deductible with a maximum out of pocket cost per year of $10,000. If each day in the hospital cost $4,500 and there are also lab fees and other related charges totaling $1,850, what amount is Sherisa responsible for?
