The percentage of men age 65 years and older in the workforce from 1950 (t = 0) through 2000 (t = 50) is approximately P(t) = 0.0135t2 − 1.093t + 41.3 (0 ≤ t ≤ 50). Show that the percentage of men age 65 years and older in the workforce in the period of time under consideration was smallest around June 1990.
