Explanation:

A stem - and - leaf plot shows data. The stem is the tens digit and the leaf is the units digit.
Step2: Count data in range
For numbers from 60 - 69, there are 2 values (61, 64). For 70 - 79, there are 6 values (71, 72, 74, 75, 75, 77). For 80 - 89, there are 4 values (84, 86, 86, 88). For 90 - 99, there is 1 value (90).
Step3: Sum the counts
$2 + 6+4 + 1=13$.
