To find the percentage of dresses that are red, you first need to determine the total number of dresses.

Here's how you calculate it:

  1. Add up all the dresses:
    • Red: 14
    • Black: 37
    • Blue: 22
    • White: 56
    • Other: 33

Total = 14 + 37 + 22 + 56 + 33 = 162

  1. Now, to find the percentage of red dresses, use the following formula: \[ \text{Percentage} = \left( \frac{\text{Number of Red Dresses}}{\text{Total Number of Dresses}} \right) \times 100 \] Plugging in the numbers: \[ \text{Percentage} = \left( \frac{14}{162} \right) \times 100 \approx 8.64% \]

Rounding to the nearest percent, the percentage of red dresses is approximately 9%.

So the answer is 9%.
