Concept explainers
In each of the next set of problems, assume that the data can be modeled bya straight line and that the trend continues indefinitely. Use two data points tofind such a line and then estimate the requested quantities. (See Example1.)
Tax Returns The approximate number (in millions) of individualelectronically filed tax returns filed with the Internal Revenue Service(IRS) in the year 2005 was 68.5, and it was 123.7 in 2016. Let [&x=5&]correspond to the year 2005, and estimate the number of electronicallyfiled returns in 2010 and 2014. Hint: Round slope to two decimalplaces. (Data from: U.S.Internal Revenue Service.)
