What does the sun product of price times quantity divided by average price 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:

$$
\begin{array}{c|lcr}
n &amp; \text{Factory A Generation of good x} &amp; \text{Factory B Generation of good x} &amp; \text{Market price for good x} \\
\hline
1 &amp; Q1 &amp; Q1 &amp; P1 \\
2 &amp; Q2 &amp; Q2 &amp; P2 \\
3 &amp; Q3 &amp; Q3 &amp; P3 
\end{array}
$$

Thank you!
Note that $Q_i P_i$ is the total revenue from good $i$. So dividing total revenue from all goods by the amount produced of all of them should give us something like "average revenue per item produced"?
