Using U.S. Department of Health and Human Services data for selected years from 1960 and projected to 2024, the national out-of-pocket expenditures for health care H can be modeled by

H = 16.5e^0.0583t

where t is the number of years after 1960 and H is in billions of dollars. Graph this equation with a graphing utility to show the graph through the year 2030.
