Stem Leaf

1 5 9

2 2 3 7 8

3 5

4 0 1 4

5 0 4

7 0

Key: 1|5 = 15

The answer is 44.

Step-by-step explanation:

The stem-and-leaf plot is a way to list out numbers over a big range by dividing into sub-groups ("stems"). If you do not know how the numbers are represented, they will look totally incomprehensible and there is no way to make any sense; as shown in the other answer.

The key is given 1 | 5 = 15

So the table is showing the following numbers:

15, 19

22, 23, 27, 28

35

40, 41, 44

50, 54

70
