Solve.The following table shows per capita health care expenditures (in dollars) from 2003 to 2008. 
The logarithmic model that fits this data is E = f(x) = 3130 + 720 ln x, where E represents the per capita health care expenditures and x is the number of years since 2002. Use this model to predict in what year health care expenditures will reach $5,400.
