solution

Pairs of shoes per store
Stem	Leaf
2	7
3	4 7 8
4	0 5 5 7
5	2 6
6	1 4 6
7	0 2 6 7
8	5 6 9

Look at the last row of the stem-and-leaf plot. The last row has the highest stem. The stem for the last row is 9.

Now find the highest leaf in the last row. The highest leaf is 0.

The largest number of pairs of shoes has a stem of 9 and a leaf of 0. Write the stem first, then the leaf: 90.

The largest number of pairs of shoes is 90 pairs of shoes.
