1) From 1990 to 2010 the numbers (in ten thousands) of female F and male M employees from the ages of
16 to 19 in the United States can be modeled by
F(t) = -0.7+2 + 10t + 37 and
M(t) = .013 – 0.912 + 11t+37
where t is the number of years since 1990
What is the model for the total number of employees?
How many total employees does the model say there were in 1994?
