Using the information from Problem 8-32, assume that the nursing administrator expected 400 patients for flu shots and 1,600 for flu treatment. The medical group typically charges $50 for a flu shot and $80 for treating a flu patient. Actually, the group had 1,200 patients who received flu shots and 1,400 who had the flu and received treatment. On average, it was able to collect $55 per flu shot and $70 per flu patient. Compute the volume, mix, and price revenue variances. How did things turn out for the group considering just revenues? How did they turn out from a profit perspective?
