I can't figure this out. who do you find the price for 2012 ? also the paragraph above states Exercise 4.

In December 2012, you are estimating a reasonable price for an office light

fixture requirements contract. There has been a requirements contract awarded for a

contractor to supply this fixture in each of the past 3

years. Each year the estimated quantity

has been approximately 10,000 units

, with the same terms for delivery and warranty. Market

research indicates the most closely related NAICS Code for this requirement is 33512,

"Nonresidential Electric Lighting Fixtures."

In fact, you verified with local suppliers that

they also use this NAICS code in their business forecasting. Using historical prices and

available index numbers from the DOL's PPI Detailed Reports(given below, for NAICS Code 333512),

estimate a reasonable unit price for the fixture.
