Explanation:

Step1: Count the number of boys who like skinny jeans

From the dot - plot for boys (A), count the number of dots. There are 7 dots.

Step2: Calculate the percentage

The formula for percentage is \(\frac{\text{Number of boys who like skinny jeans}}{\text{Total number of boys}}\times100\%\). The total number of boys is 20. So the percentage is \(\frac{7}{20}\times100\% = 35\%\)
