Explanation:

Step1: Calculate total student cars

First, find the total number of cars owned by students. Add the number of American, European, and Asian cars owned by students: \(105 + 31 + 55 = 191\).

Step2: Calculate percentage of American cars among student cars

The number of American cars owned by students is 105. To find the percentage, use the formula \(\frac{\text{Number of American student cars}}{\text{Total student cars}} \times 100\). So, \(\frac{105}{191} \times 100 \approx 54.97\), which rounds to 55.0.

Answer:

55.0%
