Answer:
The correct answer is letter "C": $2,883.
Step-by-step explanation:
In Jane's case, we could calculate her average monthly income by adding all her recent monthly earnings and dividing them by the number of months we have considered for the calculation. The average or central average is the mathematic value obtained after adding up all variables in a study and dividing the result with the number of variables.
In the example:
Average monthly salary = (January + February + March + April + May) / 5
Average monthly salary = ($2,271 + $2,397 + $3,199 + $2,050 + $4,500) / 5
Average monthly salary = $2,883.40
Thus, the closest to Jane's monthly average salary is $2,883.
