If plotted, the following sales series would appear curvilinear. This indicates that sales are increasing at a somewhat constant annual rate (percent). To fit the sales, therefore, a logarithmic equation should be used.

 Year Sales (\$ millions) 2007 8.0 2008 10.4 2009 13.5 2010 17.6 2011 22.8 2012 29.3 2013 39.4 2014 50.5 2015 65.0 2016 84.1 2017 109.0

1) Determine the logarithmic equation.

y = _____ + ______t

2) Determine the coordinates of the points on the logarithmic straight line for 2007 and 2014.

Points (antilog) for 2007: _____

Points (antilog) for 2014: ______

3) By what percent did sales increase per year, on the average, during the period from 2007 to 2017?

Increased sales: _____%

4) Based on the equation, what are the estimated sales for 2018?

Estimated sales (antilog) \$_______ millions
