A country club usually only allows members to purchase tickets for its celebrity golf
tournament, but the club is considering allowing nonmembers to purchase tickets this
year. The demand and supply schedules are as follows:

$15800400600
$20600300600

Suppose that a worker in Boatland can produce either 5 units of wheat or 25 units of
fish per year, and a worker in Farmland can produce either 25 units of wheat or 5 units
of fish per year. There are 30 workers in each country. No trade occurs between the two
countries. Boatland produces and consumes 75 units of wheat and 375 units of fish per
year while Farmland produces and consumes 375 units of wheat and 75 units of fish per
year. If trade were to occur, Boatland would trade 90 units of fish to Farmland in
exchange for 80 units of wheat. If Boatland now completely specializes in fish
production, how many units of fish could it now consume along with the 80 units of
imported wheat?
