Accepted Answer

101.4. Look at Q1 on the chart and read each category's bar. Fiction = 15. Biography = 110. Children's = 128. Non-Fiction = 88. Academic = 166. Add all 5 categories: 15 + 110 + 128 + 88 + 166 = 507. Average = total divided by 5 categories: 507 / 5 = 101.4. Check: 101.4 x 5 ~ 507. So the average books sold across all categories in Q1 is 101.4.
