Answer
$R(p)=0.0009p^{3}-0.63p^{2}+245p\qquad $million dollars/year
$R(60)\approx 12.6$ billion dollars/year
Work Step by Step
Revenue= (price)$\times$(quantity)
$R(p)=p\cdot q(p)=p[0.0009p^{2}-0.63p+245]$
$R(p)=0.0009p^{3}-0.63p^{2}+245p\qquad $million dollars/year
If p=60,
$R(60)=0.0009(60)^{3}-0.63(60)^{2}+245(60)\approx 12,626$
$\approx 12.6$ billion dollars/year
