Answer :
In order to find the average, you have to find the total, and then divide by the amount of days, which in this case is 5. The total is 395/5 = 79.
Therefore, the average number of pies sold each day is 79
[tex]average=\frac{78+96+40+104+77}{5}=\frac{395}{5}=79\\\\
They\ sold\ 79\ pies\ per\ day.[/tex]
