Final answer:
The inverse demand function for CDW's cameras over the last couple of months can be determined based on PC Connection's price matching behavior.
Step-by-step explanation:
The inverse demand function for CDW's cameras over the last couple of months can be determined based on the given information about PC Connection matching price changes and not matching price increases.
When PC Connection matches CDW's price changes, the inverse demand curve for CDW's cameras is given by p = 1,400 - 2q.
When PC Connection does not match price changes, the inverse demand curve for CDW's cameras is given by p = 1,100 - 0.5q.
