peanuts

key idea

In a stem-and-leaf plot, the stem tells the first part of the number and the leaf tells the last digit of the number.

solution

Peanuts per bag of trail mix
Stem	Leaf
1	6 9
2	2 8
3	5 8
4	2
5	1 2 3 4
6	0 2 2 4 8 8

Look at the first row of the stem-and-leaf plot. The first row has the lowest stem. The stem for the first row is 1.

Now find the lowest leaf in the first row. The lowest leaf is 6.

The smallest number of peanuts has a stem of 1 and a leaf of 6. Write the stem first, then the leaf: 16.

The smallest number of peanuts is 16 peanuts.
