Furthermore, Jack calculates that he must provide coverage for three 6-hour shifts per day and each shift must have three audioiogists to meet demand for screening tests. He anticipates hiring nine people to provide coverage for the duration of the fair. The hourly rate for audiologists is $37.50. People who fail the initial screening at the fair are referred to an audiologist for a diagnostic test. Jack assumes in his calculations that all people who are referred for diagnostic testing foilow up with an audiologist in one of Timberline Health's hearing centers. Initial screening tests at the fair are free; however, Timberline Health charges $57.00 for a diagnostic hearing test, which costs the organization $24.00. Using past sales data and industry metrics, Jack forecasts that of the total number of people diagnosed with hearing loss at hearing centers oniy 20% will purchase hearing aids (NIH, 2010). He reviews sales and margin data from the prior year to identify the product mix for his calculations as indicated in Table 2.
