Part A: There are 20 flowers in the garden, as there are 20 data points on the line plot.
Part B: There are 3 more flowers with a height of 7 1/4 inches or greater than with a height of 7 inches or less. To see this, count the number of data points to the right of the vertical line at 7 inches, which is 6, and the number of data points to the right of the vertical line at 7 1/4 inches, which is 9. Then, subtract the numbers to get 9 - 6 = 3. Therefore, the answer is C. 3.
