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.

complete the table
t 2010 2020 2030 2040 2050
p

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%.

  • algebra -

    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.
