because of a slump in the economy, a company finds thatr its annual revenue have dropped from $724,000 in 2006 to $632,000 in 2008. if the revenue is following an exponential ppattern of decline, what is the expected revenue for 2009? (Let t=0 represent 2006.)

revenue=last year*e^kt
solve for k (given t=2, and the figures above.
k2=ln(632/724)
I get k to be.0680
Now solve for 2009
revenue=reventue2006 * e^(.0680t) where t is three years.
