For the years 2010 to 2050, the projected percentage P of the U.S. population that will be 18 to 24 years old during year t is estimated by P= -0.025t+ 60.35.

use the table to find the year when the percentage of the population that is 18 to 24 years old is expected to be 9.4%.
P = -0.025x + 80.35.
P = -0.025*2010 + 60.35 = 10.1.
So,10.1 % of the population is expected to be in the 18 t0 24- year range in year 2010.
The student should finish the table.
-0.025t + 60.35 = 9.4
Solve for t.
