To find the average weekly food expense of the Johnson family during the 4-week period, you need to add up the total amount spent on groceries and divide it by the number of weeks (which is 4 in this case).
The total amount spent on groceries over the 4-week period is $72.84 + $61.20 + $75.48 + $68.76 = $278.28.
To find the average, divide the total amount 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.
So, the correct answer is 2] $69.57.
