Explanation

Total I-pod users = 12200 + 9500 + 14960 + 29750 + 10550 = 76960. Total Stereo System users = 33800 + 45360 + 36200 + 21500 + 30000 = 166860. Percentage = (76960 / 166860) * 100 = 46.1224... which rounds to 46.12.

AI explanation

Sum the total number of I-pod users across all cities by adding 12200 + 9500 + 14960 + 29750 + 10550 to get 76960. Then, sum the total number of stereo system users by adding 33800 + 45360 + 36200 + 21500 + 30000 to get 166860. Apply the percentage formula by dividing 76960 by 166860 and multiplying the result by 100, which equals approximately 46.12 percent.
