A turkey is removed from the oven when its temperature reaches 175°F and is placed on a table in a room where the temperature is 70°F. After 10 minutes the temperature of the turkey is 161°F and after 20 minutes it is 149°F. Use a linear approximation to predict the temperature of the turkey after 30 minutes.
What will be an ideal response?
136°F
