The incomes are indeed small xD
You are asked to find the average income, 

average of lets say numbers 45, 46, 48, and 50 is
(45+46+47+50)÷4
(average= add all numbers up, and divide the sum by the NUMBER-OF-NUMBERS)
in this case there are 4 numbers, and the sum is equal to 188.
Divide this sum by 4,
188÷4   and you get 47.

Thus the average of the numbers (45, 46, 47 and 50) is equal to `  47  `
(the average doesn't have to be one of the numbers, it just came out to be 47 from adding and dividing by 4)
