Question

In 1994, the average price of a new domestic car was $16,930.  In 2002, the average price was $19,126.  Based on a linear model, what would be the approximate predicted average price for 2008?  
    $23,000  
   $21,300  
   $20,800  
   $18,600

l · Answer

2002-1994 = 8 year
2008-1994 = 16 years
16/8 = 2

19126 - 16930 = 2196 dollars in 8 years
2196 * 2 = 4392 dollars in 16 years

So the price is 16930 + 4392 = 21322 dollars in 2008
