To calculate the mean absolute deviation, we first need to find the mean of the data.

Mean = Sum of all values / Number of values 
Mean = (32,150,000 + 28,500,000 + 22,350,000 + 25,600,000 + 31,250,000) / 5 
Mean = 27,370,000

Next, we calculate the absolute deviation of each value from the mean:

|32,150,000 - 27,370,000| = 4,780,000 
|28,500,000 - 27,370,000| = 1,130,000 
|22,350,000 - 27,370,000| = 5,020,000 
|25,600,000 - 27,370,000| = 1,770,000 
|31,250,000 - 27,370,000| = 3,880,000

Then, we calculate the average of these absolute deviations:

Mean Absolute Deviation = (4,780,000 + 1,130,000 + 5,020,000 + 1,770,000 + 3,880,000) / 5 
Mean Absolute Deviation = 15,580,000 / 5 
Mean Absolute Deviation = 1,341,460

Therefore, the answer is C) 1,341.46.
