Hello, 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. When Dena and Andrew specialize and trade, would trading sh for pineapples on a 1 for 1 basis be acceptable to Dena without making her worse off? Briey explain. B. What is the most that Dena would be willing to pay in order to trade for the good that she does not have a comparative advantage in producing? (assume she would be willing to trade as long as she is not made worse off by the trade) C.
