Solve the problem.
-A pie comes out of the oven at $275 ^ { \circ } \mathrm { F }$ and is placed to cool in a $70 ^ { \circ } \mathrm { F }$ kitchen. The temperature of the pie $T$ (in ${ } ^ { \circ } \mathrm { F }$ ) after $t$ minutes is given by $T = 70 + 205 e ^ { - 0.018 t }$. The pie is cool enough to cut when the temperature reaches $130 ^ { \circ } \mathrm { F }$. How long will this take? Round to the nearest minute.
A) 68 minutes
B) 25 minutes
C) 56 minutes
D) 85 minutes
