I have a very simple question, what is the meaning, if any, of this?
I.e. Economically what does the following calculation mean?
$$ \left(\frac{(Q1\cdot P1)+(Q2\cdot P2)+(Q3\cdot P3)}{Q1 + Q2 + Q3}\right) $$
Consider the values being in a table like the one shown below:
$$ \begin{array}{c|lcr} n & \text{Factory A Generation of good x} & \text{Factory B Generation of good x} & \text{Market price for good x} \\ \hline 1 & Q1 & Q1 & P1 \\ 2 & Q2 & Q2 & P2 \\ 3 & Q3 & Q3 & P3 \end{array} $$
Thank you!
