Ms. Nguyen decided to make a hot chicken panini by putting her sandwich into a griddle. She took the sandwich off when it Was done such that the sandwich temperature was 85'C. The room temperature was 23°C. Unfortunately, her kids called her away and she had to leave her nicely made sandwich on the counter. After 30 minutes, she was able to return to her sandwich which was cooled. The cooked chicken starts having bacteria grow on it when its temperature is below 60°C. 

a. The function of cooling the sandwich can be modeled using the formula: 

T (t) =-- a (0.5)* +c
