An average number is a single number taken as a representative of a list of numbers which is usually the central value in a data set. Often average refers to the ‘arithmetic mean’, the sum of the numbers divided by how many numbers are being averaged, or the sum of the terms divided by the number of terms

Calculated by dividing the sum of the values in the set by their number.

Total Number of Months = 3

Combined Expenditure of all 3 months = Expenditure of September + Expenditure of October + Expenditure of November

Expenditure of 3 months combined = 1988 + 2234.5 + 2099 = $6321.5

The ‘Average’ expenditure would be equal to the sum of the expenditure of all three months divided by the number of months

Average Monthly = Expenditure of all months/ Total Number of months

Average Monthly Expenditure = 6321.5/3 = 2107.166667 = $2107.17

Hence answer is B
