stem leaf
0 0, 1, 3, 3
1 3, 3, 4, 6
2 2, 5, 5, 6, 7
3

Explanation:

Step1: Understand "at least 21"

"At least 21" means 21 or more. So we look at stems ≥ 2 (since stem 2 represents numbers in the 20s, stem 3 represents 30s, etc.).

Step2: Analyze stem 2

For stem 2, the leaves are 2, 5, 5, 6, 7. Each leaf represents the ones digit. So the numbers are 22, 25, 25, 26, 27. That's 5 days.

Step3: Analyze stem 3

For stem 3, there are no leaves (empty). So 0 days.

Step4: Sum the days

Add the number of days from stem 2 and stem 3: 5 + 0 = 5.

Answer:

5
