Suppose an investor purchased x ounces of gold in January 2006 at the prevailing price of $549.86 per ounce and then sold this amount of gold in January 2010 for $1112.30 per ounce. (a) Find an equation to express the realized gain, y, in terms of x. (b) Find the point of intersection of the graph of this equation with the graph y= 10,000 to determine the number of ounces of gold that would result in a gain of $10,000
