David Lum operates two pharmacies, one near the hospital and a second near the outpatient surgery clinic. Lum categorizes sales revenues as prescription medicine, over-the-counter medicine, or non-medical sales. The monthly revenues from each store for the first five months of the year are shown in the two tables below. Using Figures 24-8a and 24-8b, construct two component bar graphs for the respective stores. Write labels where necessary.
