PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!! I CANNOT RETAKE THIS!!

$T(t) = T_s + (T_0 - T_s)e^{-kt}$

$T(t) - T_s = (T_0 - T_s)e^{-kt}$

$\dfrac{ T(t) - T_s}{T_0 - T_s} = e^{-kt}$

$\ln \dfrac{ T(t) - T_s}{T_0 - T_s} = -kt$

$k = - \dfrac{ \ln \dfrac{ T(t) - T_s}{T_0 - T_s} }{t}$

OK now let's plug in the numbers.

We have t=15 minutes, T_0 = 80 C, Ts = 50, T(15)=60 C,

$k = - \dfrac{ \ln \dfrac{ 60 - 50}{80 - 50} }{15 \textrm{ min}}$

$k = - \frac{1}{15} \ln \frac 1 3$

$k = \frac{1}{15} \ln 3$

$k \approx 0.07324$ per minute
