Jose Glass had a car accident last month and spent a night in the hospital. The bill came yesObjs. 1, 5 terday, and when he looked it over he noted that he had been charged \(\$ 7\) for a single aspirin. Believing it was a clerical error, Jose called the hospital and was told that the charge was correct. The person he spoke to in the billing department said that part of the charge was "overhead allocation" that included purchasing, handling, and other support-related costs. How does overhead allocation affect the cost of aspirin?
