I need help with this please.

Dena and Andrew nd themselves on a deserted island. The only two activities available are shing and nding pineapples. In a full day. Dena can catch 8 sh or nd 12 pineapples or some linear combination of the two: in the same time. Andrew can catch 5 sh or nd 10 pineapples or some linear combination of the two. A. What are each individual's marginal costs of shing and nding pineapples? (must provide the correct answer for full credit. no additional work is necessary) B. Who has an absolute advantage in sh production? Who has an absolute advantage in nding pineapples? Who has a comparative advantage in sh production? Who has a comparative advantage in nding pineapples? Briey explain your reasoning. C. Assume, initially, that there is no possibility of trade between Dena and Andrew. If both Dena and Andrew wish to consume 2 sh each, what is the most pineapples that each of them would be able to produce and consume in addition to the 2 sh? Briey explain how you derived your answer. D. Now assume that specialization and trade is possible between Dena and Andrew. If they each want to continue to consume the same number of sh indicated in part {c}, how many pineapples would they be able to collectively consume each day? Briey explain how you derived your
