In 2008, the price of soybeans was $3.50 a bushel, and the Jones family farm planted 7,500 acres of

them. In 2009, although the price of soybeans fell to $3.25 a bushel, the Jones family farm planted 8,200

acres of them. Use the concepts of a shift in the supply curve versus a movement along the supply curve

to explain why this increase in soybean acreage does not represent a violation of the law of supply.
