Accepted Answer

To find the average growth rate from October to December, we first calculate the growth rates for October to November and November to December.

Circulation in October = 200,189
Circulation in November = 204,933
Circulation in December = 211,885

Growth rate from October to November = ((204,933 - 200,189) / 200,189) * 100 = (4,744 / 200,189) * 100 ≈ 2.37%

Growth rate from November to December = ((211,885 - 204,933) / 204,933) * 100 = (6,952 / 204,933) * 100 ≈ 3.39%

Average growth rate = (2.37% + 3.39%) / 2 = 2.88%

Rounded to one decimal place, the average growth rate is 2.9%.
