Explanation:

Step1: Identify relevant data

For stems 4, 5, 6 we check leaves.

Step2: Count for stem - 4

For stem 4, leaves 4 and 5 satisfy the condition. So 2 shelves.

Step3: Count for stem - 5

For stem 5, leaves 1, 8, 9 satisfy the condition. So 3 shelves.

Step4: Count for stem - 6

For stem 6, leaf 6 satisfies the condition (9 is not in the range). So 1 shelf.

Step5: Sum up

Total number of shelves = 2 + 3+ 1=6

Answer:

6
