A medical insurance service reports that health-care expenditures per capita were $2823 in 1990 and $3365 in 1993. Assume that this rate of growth continues. (a) Find the three-year growth factor a. (Round your answer to two decimal places.) Find an exponential model  E(x) = Cax  for the annual health-care expenditures per capita, where x is the number of three-year time periods since 1990. (b) Use the model found in part (a) to predict health-care expenditures per capita in 1996 and in 2002. (Round your answers to the nearest cent.)
