On Gordon Island, there is a small population of 80 (politically-correct) fishers. Each can fish in the (almost land-locked) lagoon, or fish outside the lagoon, on the Great Bank. The amount of fish (in kilograms) harvested from the lagoon (the yield of fish) each period depends on the number fishing there. Yield from the lagoon (YL) depends on the number of fishers in the lagoon, FL, and can be described with the function Y1 (F) = 500F, -10F; Yield from fishing on the Great Bank (YB) depends on the number of fishers there (FB), and can be approximated with the (linear) function YB (FB ) = 10OF An advocate of "letting the market work," Shea Hearn (the dictator of Gordon Island) imposes license fees on all fishers who choose to operate in the lagoon. If the price of landed fish is $5, what should be the price of a license (to ensure that the maximum yield of fish is obtained)? Question 10 options: 1) No more than $500 2) More than $500 but not more than $1,000 3) More than $1,000 but not more than $1,500 4) More than $1,500 but not more than $2,000
