Hello!
As the demand for a good increases, the demand for a related good also increases. As the demand for a good decreases, then the demand for a related good decreases as well. 
For example, if a new DVD player is released, then consumers will want the new product, therefore increasing demand for it. Because the demand for the player goes up, the demand for DVDs will also go up because consumers will want more DVDs to use with their DVD players. In this case, the DVD is the related good. 
On the other hand, the demand for a related good will decrease if the demand for the main good decreases. For example, if demand for potatoes were to decrease, then the demand for potato peelers would also decrease. This is because people would not need potato peelers if they do not purchase potatoes. 
I hope this helps you! Have a lovely day!

ARPANET development began with two network nodes which were interconnected between the Network Measurement Center at the University of California, Los Angeles (UCLA) Henry Samueli School of Engineering and Applied Science.</span>

Answer:
Total equivalent units= 11,890
Explanation:
Giving the following information:
Assembly Department completes 10,200 gadgets and transfers them to Finished Goods Inventory. 
The Assembly Department has 2,600 gadgets in the process that are 65% complete for conversion.
<u>To calculate the equivalent units, we need to multiply the % complete for the number of units started:</u>
Units completed= 10,200
Units in ending inventory= 2,600*0.65= 1,690
Total equivalent units= 11,890
