Multiple Choice

Solve the problem.
-After introducing an inhibitor into a culture of luminescent bacteria, a scientist monitors the luminosity produced by the culture. Use a graphing utility to fit a logarithmic function to the data. Predict the luminosity
After 20 hours. $\begin{array}{l|ccccccc}\text { Time, hrs } & 2 & 3 & 4 & 5 & 8 & 10 & 15 \\\hline \text { Luminosity } & 77.4 & 60.8 & 54.5 & 45.8 & 30.0 & 24.3 & 10.5\end{array}$

A) $y = 98.75 - 32.66 \ln ( x ) , 0.91$
B) $y = 107.55 - 41 \ln ( x ) , - 15.27$
C) $y = 112.97 - 45.97 \ln ( x ) , - 24.74$
D) $y = 100.5 - 32.7 \ln ( x ) , 2.54$
