The nation's corn crop is ripe in the fields, but none of it is harvested. It is known that if it is all harvested. the total amount of corn harvested will be 20 million tons. The cost of harvesting the corn and bringing it to market {rather than leaving it in the fields and glowing it down] is $20 per ton. Farmers have spent $30 per ton on preparingT fertilizing, and cultivating the corn fields. On a graph where quantity is on the horizontal axis {measured in millions of tons) and the price is on the vertical axis {measured in dollars per ton), the sugglyr curve in late August for this year's corn delivered at harvest time consists of (a) a line running from {0,0} to (0.20): a line from [0,120] to {20,20}, and a line running vertically straight up from {20,20}. {b} a line running from (0,0) to {20. 0} and a line running vertically straight up from {20,0}.

The demand curve for this year‘s oorn harvest in the market desoribed in the previous question is given by the equation P=1DD_50, where Q is the millions of tons of corn that are sold and P is the price per ton of corn.

A drought in the southwest reduced the sUppiy of watermelons produced in Arizona this year. Despite their reduced crop, watermelon growers in Arizona actually earned more total revenue this year than last year. Assuming the demand curve did not change. the increase in total revenue is evidence that (a) the price elasticity of supply for watermelon is between D and +1.0. {h} the price elasticity of demand for watermelon is between -'l.fl and D. (o) the price elasticity of supply for watermeion is greater than +1.0. [d] the price elasticity of demand for watermelon is less than - 1.0. 8. Every day at the local fish market. there are 100 demanders who are willing to pay up to $30 for a fish, 100 demanders who are willing to pay up to $20 for a fish. and 10D demanders who are willing to pay up to S10 for a fish. No demander wants more than one fish. There are 20 fishermen who sell fish in this market. Every day the fishermen arrive with the day's catch. Each fisherman has spent $100 on fuel for his boat the night before, but they have no other costs. Fish that are not sold on the same day they are caught will rot and become worthless. Every day the fish market reaches a competitive equilibrium price for the day*s fish. On Monday each fisherman caught 3 fish.

Assuming that the fishermen all continue to fish. what would be the effect or this increase on the price of fish on those days when each fisherman catches 12 fish? {3} There would be no effect on price. {b} The price per fish would rise by about $12.50 per fish.
