Pablo counted the number of silver beads on each bracelet at Hillsdale Jewelry, the store where he works.

How many bracelets had exactly 71 silver beads?

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.

For the number 71, the stem is 7, and the leaf is 1. Find the row where the stem is 7. In that row, count all the leaves equal to 1.

You counted 2 leaves, which are blue in the stem-and-leaf plot above. 2 bracelets had exactly 71 silver beads.
