$C (t) = - 0.005 t^{4} + 0.139 t^{3} - 0.051 t^{2} + 1.8 t$

Step 1

Set $- 0.005 t^{4} + 0.139 t^{3} - 0.051 t^{2} + 1.8 t$ equal to $0$ .

$- 0.005 t^{4} + 0.139 t^{3} - 0.051 t^{2} + 1.8 t = 0$

Step 2

Graph each side of the equation. The solution is the x-value of the point of intersection.

$t \approx 0, 27.89695095$
