The stem-and-leaf plot below shows the total number of points different gymnasts earned in a gymnastics competition. How many gymnasts scored less than 50 points?

A. 4
B. 6
C. 7
D. 8
There are 4 gymnasts in the 30s (stem=3), 6 gymnasts in the 40s (stem=4), and none in the 50s (stem=5) who scored less than 50 points. Therefore, the answer is A. 4.
To determine the number of gymnasts who scored less than 50 points, we need to count the leaf values that are less than 5.
From the given stem-and-leaf plot, we can see that there are 4 leaf values less than 5: 2, 2, 4, 1.
Therefore, the correct answer is A. 4 gymnasts scored less than 50 points.
