The stem-and-leaf plot shows kilometers walked by participants in a charity benefit walk. Use it to answer the questions.
A stem and leaf plot shows the number of kilometers walked for charity.
The plot is titled 'Kilometers Walked for Charity.' The numbers 12, 13, 14, 15, 16, and 17 are in a vertical column to the left of a vertical line.
· On the same line as 12 but on the right of the vertical line are the numbers 3, 3, 6, 7, 9, and 9.
· On the same line as 13 but on the right of the vertical line are the numbers 1, 1, 4, 5, and 5.
· On the same line as 14 but on the right of the vertical line are the numbers 0, 0, 2, 3, 3, 8, 8, and 9.
· On the same line as 15 but on the right of the vertical line are the numbers 2, 2, 2, 2, 2, 3, 5, 5, and 7.
· On the same line as 16 but on the right of the vertical line are the numbers 4, 5, 5, 9, and 9.
· On the same line as 17 but on the right of the vertical line are the numbers 3 and 5.
The key to the stem and leaf plot identifies that 12 vertical line 3 means 12.3.

GREAT JOB
To answer these questions using the stem-and-leaf plot:
a. How many people participated in the walk?
To determine the number of people who participated in the walk, you need to count the total number of entries in the stem-and-leaf plot. Each entry represents one participant.
Counting the entries, we have:
- 6 entries for the stem 12
- 5 entries for the stem 13
- 8 entries for the stem 14
- 9 entries for the stem 15
- 5 entries for the stem 16
- 2 entries for the stem 17
Adding these up, we get:
6 + 5 + 8 + 9 + 5 + 2 = 35
Therefore, 35 people participated in the walk.
b. How many of the walkers traveled more than 14 kilometers?
To determine the number of walkers who traveled more than 14 kilometers, you need to add up the entries for stems 15, 16, and 17.
Counting the entries, we have:
- 9 entries for the stem 15
- 5 entries for the stem 16
- 2 entries for the stem 17
Adding these up, we get:
9 + 5 + 2 = 16
Therefore, 16 walkers traveled more than 14 kilometers.
