A turkey is removed from the oven when its temperature reaches $175^{\circ} \mathrm{F}$ and is placed on a table in a room where the temperature is $70^{\circ} \mathrm{F}$ . After 10 minutes the temperature of the turkey is $160^{\circ} \mathrm{F}$ and after 20 minutes it is $150^{\circ} \mathrm{F}$ . Use a linear approximation to predict the temperature of the turkey after $30$ minutes.
A) $160$
B) $36$
C) $134$
D) $135$
E) $140$

The temperature decreases by 10 degrees every 10 minutes (from 160 to 150 in 10 minutes). So, after another 10 minutes (30 minutes total), it would decrease by another 10 degrees, reaching 140 degrees.
