Answer
$3150$ million dollars
Work Step by Step
Need to find $f(27)$.
We have $x=2012-1985=27$ years
Thus,
$f(27)=350(27)^\frac{2}{3}$
Since, the power raised to a each base gets multiply such as $(ab)^n=a^nb^n$
Thus,
or, $=350(3^3)^\frac{2}{3}$
or, $=350(3)^\frac{6}{3}$
This implies that
or, $f(27)=3150$ million dollars
