Per capita expenditures for U.S. health care The following table shows the amount spent per person for health care in the United States for selected years from 2002 and projected to 2024. These data can be modeled by
(a) Find the instantaneous rate of change of per capita health care expenditures (to the nearest dollar) for 2010 and 2020.
(b) Interpret the rate of change for 2020 found in part (a).
(c) Use the data to find the average rate of change from 2018 to 2020. How well does this approximate the rate of change in 2020?
Year | $ per Person | Year | $ per Person |
2002 | 5563 | 2014 | 9695 |
2004 | 6331 | 2016 | 10,527 |
2006 | 7091 | 2018 | 11,499 |
2008 | 7944 | 2020 | 12,741 |
2010 | 8428 | 2022 | 14,129 |
