69.57
To find an average get a total of the entries and divide by the number of entries.
In this problem get a total of the expenses for the 4 weeks. Then, take that total and divide by 4 to get the average.
Hope that helps!

Well, it seems like the Johnson family is really "food"tastic with their expenses! Let's do some calculations here, no clowning around! To find the average weekly food expense of the Johnson family over a 4-week period, we add up the amounts they spent on groceries each week and then divide by the number of weeks.
So, $72.84 + $61.20 + $75.48 + $68.76 = $278.28 (total amount spent in 4 weeks)
Now, we divide this total by 4 (since it's a four-week period) to get the average:
$278.28 / 4 = $69.57
Therefore, the average weekly food expense for the Johnson family over the 4-week period is approximately $69.57. That's a lot of dough, but hey, you can't put a price on good food and happy tummies!
To find the average weekly food expense of the Johnson family during the 4-week period, you need to sum up the expenses of each week and then divide it by 4 (the number of weeks).
1. Add up the expenses of each week: $72.84 + $61.20 + $75.48 + $68.76 = $278.28
2. Divide the total expense by the number of weeks: $278.28 / 4 = $69.57
Therefore, the average weekly food expense of the Johnson family during the 4-week period is $69.57.
