To figure this out all you need to do is add all of the grocery bills and divide that number by 4...
The average bill for groceries is $204.
Given that, the last four weeks' bills are $203, $195, $180 and $238.
We need to find the average bill.
In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.
The formula to find the average of numbers is Average=Sum of all the observations/Total number of observations.
Now, the sum of all the observations=203+195+180+238=816
Total number of observations=4
So, Average=816/4=204
Therefore, the average bill for groceries is $204.
