A Valve on a Storage Tank Is Opened for 4 $\ln R = - 0.6155 t + 15.0609$

Multiple Choice

A valve on a storage tank is opened for 4 hours to release a chemical in a manufacturing process. The flow rate R (in liters per hour) at time t (in hours) is given by the linear Model $\ln R = - 0.6155 t + 15.0609$ Write the linear model in exponential form.

A) $R = - 15.0609 e ^ { - 0.6155 t }$
B) $R = 8.0609 e ^ { - 0.6155 t }$
C) $R = 15.0609 e ^ { - 0.6155 t }$
D) $R = 3,474,287.5695 e ^ { - 0.6155 t }$
E) $R = 3,474,287.5695 e ^ { 0.6155 t }$
