Given that the fishing activity of a bay is described by the following:
Boats Total Catch(lbs)
1 60
2 100
3 3130
4 150
5 160
6 150
If fish sell in a perfectly competitive market at $2.5 per pound and the total cost per boat is $90 calculate: (a) the number of boats that would not violate economic efficiency and (b) the actual number of boats under open access.
