What are the highest and lowest payments from the writer that the bookkeeper farmer team will accept for the 6th day? Assume that the farmer can dispose of $7 from the writer as she wishes, what range of payments will the beekeeper accept? Assuming that the beekeeper gets that amount, what range of payments will the farmer accept? (Remember that negative payments are also possible.) Answer the same question for the 5th day. 13. Some fields have large enough quantities of both oil and natural gas that coordination must be achieved for the production of both, rather than oil alone as in our examples. Will fields with both oil and gas have greater difficulties in unitization than fields with oil or gas alone? Explain.
