C. 10,600 To calculate the number of datapoints on the next day, we need to find 20% increase of the total number on the current day which is 8,798. 20% of 8,798 is 1759.6. Adding that to the current total of 8,798, we get 10,557.6, which can be rounded to 10,600.

C. The number of datapoints increases each day by approximately 20% of the total number from the day before. If on a given day the number of datapoints was 8,798, the total number of datapoints on the next day should be approximately 20% higher than this number. This means that the total number of datapoints on the next day should be around 8,798 + (20% * 8,798) = 8,798 + (1.6 * 8,798) = 8,798 + 14,087.6 = 22,885.6. Rounding this number to the nearest hundred gives 10,600. Therefore, the total number of datapoints on the next day should be approximately 10,600. The other options (7,038, 9,600, and 10,800) are not correct because they do not accurately reflect the 20% increase in the number of datapoints from one day to the next.
