Explanation:

Step1: Identify the shortest bar

By observing the bar - graph, the bar for red T - shirts is the shortest. The height of the red bar corresponds to 5 T - shirts sold.

Step2: Calculate the difference between black and white T - shirts

The number of black T - shirts sold is 8 and the number of white T - shirts sold is 6. The difference is \(8 - 6=2\).

Step3: Count the number of colors with at most 8 T - shirts

The colors white (6 T - shirts), red (5 T - shirts), gray (7 T - shirts) have at most 8 T - shirts sold. So there are 3 such colors.
