The stem-and-leaf plot shows the ages of customers who were interviewed in a survey by a store. **Question:** How many customers were younger than 35? **Ages of Store Customers:** ``` 1 | 0 2 3 3 3 6 8 2 | 1 1 3 4 4 5 6 8 9 3 | 2 2 4 4 5 7 4 | 1 2 3 5 8 5 | 0 3 1 5 6 6 | 2 4 5 5 7 | 3 ``` **Key:** 1 | 0 = 10 **Explanation:** This stem-and-leaf plot organizes the ages of customers in a way that shows the frequency of different age groups. The 'stem' represents the tens digit, while the 'leaf' represents the units digit of the ages. For example, the entry "1 | 0 2 3 3 3 6 8" means there are customers aged 10, 12, 13, 13, 13, 16, and 18. To find the number of customers younger than 35, count all the leaves in the stems 1, 2, and 3. - Stem 1: 7 customers (ages 10, 12, 13, 13, 13, 16, 18) - Stem 2: 9 customers (ages 21, 21, 23, 24, 24, 25, 26, 28, 29) - Stem 3: 6 customers (ages 32, 32, 34, 34) Adding these, there are 22 customers younger than 35.
