Answer 1

To calculate the average weekly food expense for the Johnson family, first add up their weekly expenses and then divide by the number of weeks.

The expenses are:

1. $72.84
2. $61.20
3. $75.48
4. $68.76

Now, let's calculate the total expense:

\[ 72.84 + 61.20 + 75.48 + 68.76 = 278.28 \]

Next, divide the total by the number of weeks (4):

\[ \text{Average weekly expense} = \frac{278.28}{4} = 69.57 \]

So, the average weekly food expense for the Johnson family during the four-week period is $69.57.
