Concept explainers
Social Security Assets As seen in the first section of this chapter, the projected year-end assets in the Social Security trust funds, in trillions of dollars, where t represents the number of years since 2000, can be approximated by
A(t) = 0.0000329t3 − 0.00450t2 + 0.0613t + 2.34,
where 0 ≤ t ≤ 50. Find the value of t when Social Security assets will decrease most rapidly. Approximately when does this occur? Source: Social Security Administration.
