The year is 1992. The VHS rental market in a small town is controlled by just two firms: East Coast Video and I<heart>Video. The two stores have virtually the same stock of videos. The inverse market demand for VHS rentals in town each week is: p = 2400 - 7Q where Q equals the total weekly rentals in town ($Q = q_1 + q_2$) Each business has a cost of renting a tape $C(q) = 1q + 100$. The owners of the two firms have made a deal to collude in setting their output levels so as to maximize their joint profits, just like a cartel. Assume they each will rent the same number of VHS tapes. How many VHS tapes does each store agree to rent weekly? In short, find the cartel output of each individual firm. Round your answer to the nearest whole number. You may upload your work for this problem for partial credit for minor errors in the calculation.

Which of the following expresses what Frye means by taking a "macroscopic" view of the bird cage/oppression? a. View the whole cage, rather than one wire; see the way in which the individual choices of members of an oppressed group have resulted in a series of connected impediments. b. Focus in on the bird itself; see a specific social group and the limitations, barriers, and double binds (etc.) that it faces. c. View one wire at a time rather than the whole cage; see individual limitations, barriers, double binds (etc.), rather than the connections between them. d. View the whole cage, rather than one wire; see the whole social context such that one can see the connections and structure between individual limitations, barriers, double binds (etc.) such that one can "see" oppression.
