Answer:
C.
Step-by-step explanation:
The range is the difference between the lowest and highest values. A stem-and-leaf plot works so that the number in the leaf column is the ones place of the beginning of the number in the stem column. So the numbers you actually have in this set are 10,12,12,22,23,24,30, and 35. The range is 35-10, so 25.
