The annual per capita out-of-pocket expenses (to the nearest dollar) for U.S. health care for selected years from 2013 and projected to 2021 are shown in the table and figure. Year Dollars 2013 1020 2015 1022 2017 1097 2019 1209 2021 1325 A coordinate plane is given. The horizontal axis is labeled Year and the vertical axis is labeled Dollars per year. Four line segments connect five points. The point (2013, 1020) is connected to (2015, 1022), which is connected to (2017, 1097), which is connected to (2019, 1209), which is connected to (2021, 1325). (a) Use n = 4 equal subdivisions and right-hand endpoints to estimate the area under the graph from 2013 to 2021. $
