Step-by-step explanation:

The average weight produced
The question is incomplete, as the required cells are not given and there are other missing details.
However, I will give a general explanation of calculating average in Excel
The required formula is:
=AVERAGE(Cell Range)
Assume the cells that contain the boxes are: cells A10 to A10010
The average will be calculated as:
=AVERAGE(A10:A10010)
You are adding 40 every time.
The 100th term is 7+(99*40)=3967
I believe 4(x - 3)=32 could help I haven’t done an equation from the unit in months so hopefully that looks familiar to you.

×

=

You then divide the numerator(top) by the denominator(bottom)

=
