1. William Gregg owned a mill in South Carolina. In December 1862, he placed a notice in the Edgehill Advertiser announcing his willingness to exchange cloth for food and other items. Here is an extract: 1 yard of cloth for 1 pound of bacon 2 yards of cloth for 1 pound of butter 4 yards of cloth for 1 pound of wool 8 yards of cloth for 1 bushel of salt

a. What is the relative price of butter in terms of wool?

b. If the money price of bacon was 20¢ a pound, what do you predict was the money price of butter?

c. If the money price of bacon was 20¢ a pound and the money price of salt was $2.00 a bushel, do you think anyone would accept Mr. Gregg’s offer of cloth for salt?
