Solve the problem.
-A drug is injected into a patient and the concentration of the drug is monitored. The drug's concentrati $C ( t )$, in milligrams per liter after $t$ hours is modeled by
$$C ( t ) = \frac { 5 t } { 3 t ^ { 2 } + 4 } \text {. }$$
Estimate the drug's concentration after 5 hours. (Round to the nearest hundredth.)
A) $0.32$ milligrams per liter
B) $0.19$ milligrams per liter
C) $1.32$ milligrams per liter
D) $1.19$ milligrams per liter

To estimate the drug's concentration after 5 hours, substitute $t = 5$ into the given function:$C ( 5 ) = \frac { 5 ( 5 ) } { 3 ( 5 ) ^ { 2 } + 4 } = \frac { 25 } { 75 + 4 } = \frac { 25 } { 79 } \approx 0.32$ milligrams per liter.
