Answer:
True
Step-by-step explanation:
To find the average of anything, you add their values together, and then divide that number by how many of them you added.
Here, you are trying to calculate monthly expenditure, so you add their values together (the sum of monthly expenditures) and then you divide it by how many months you used to add up to the sum (divided by the number of months).
Hope this helped ya! :)
