Question: SENIORS IN THE WORKFORCE The percentage of men, age 65 yr and older, in the workforce from 1950 (t = 0) through 2000 (t = 50) is approximately
P(t) = 0.0135t2 - 1.126t + 41.2 (0 ≤ t ≤ 50)
Show that the percentage of men, age 65 yr and older, in the workforce in the period of time under consideration was smallest around mid-September 1991 . What is that percent?
