Explanation
We are told that the function that models the profit made in millions per year is:
[tex]P(t)=-0.15t+12.5[/tex]Where
t is the number of years since 2005
So if we are to estimate the profit made in the year 2012
We will first have to get the value of t
[tex]\begin{gathered} t=2012-2005=7 \\ t=7 \end{gathered}[/tex]Therefore, we will put t=7
So that
[tex]P(7)=-0.15(7)+12.5=11.45[/tex]Therefore, the estimated profit will be $11.45 million
