The table shows the national expenditures for health care, in billions, in a country for selected years from 1995 with projections to 2020.  The data can be modeled by y = 134.823x + 131.267 with x equal to the number of years after 1990 and y equal to the expenditures for health care in billions of dollars. What does this model predict the expenditure will be in 2016?
