Suppose that empanadas can only be made in Argentina and that empanadas can be made at a cost of $9 per unit.

Empanadas are shipped to Canada by ship and the cost for each unit put on board is $1.

However, half of the empanadas on board rot, and need to be dumped in the ocean.

The demand for empanadas in Canada is given by:

q=10,000-p^2

If empanadas are competitively supplied, how many units will be sold in Canada?
