Suppose that people consume only three goods, tennis balls, golf balls, and bottles of gatorade.




2006 price: T= $2 G= $4 B= $1



2006 quantity: T= 100 G= 100 B= 200



2007 price: T= $2 G= $6 B= $2



2007 quantity: T= 100 G= 100 B= 200




What is the percentage change in the price of each of the three goods?
