their own protective gear and are thus price takers in the market. Both the ACCC and the
two firms under investigation agree that the market demand can be described by the
inverse demand function:
P(Q)=240-Q,
where Q is the total quantity provided by the two firms (i.e., Q=q₁ + 9B, where is the
9A
amount produced by Azure Associates and q, is the amount produced by Blue Guard).
