With data from the Social Security Trustees Report for selected
years from 1950 and projected to 2030, the number of Social
Security beneficiaries (in millions) can be modeled by
B(t) =
0.00024t3 − 0.026t2 +
1.6t + 2.2
where t is the number of years past 1950. Use
the model to find the average number of Social Security
beneficiaries per year (actual and predicted) between the following
years. (Round your answers to three decimal places.)
(a) 1984 and 2002
_______ million per year
(b) 2013 and 2020
_______ million per year
