Answer: -3.3°F

Step-by-step explanation:

In integers , we represent fall in quantity by negative numbers.

Since, the temperature at noon was 16.8°F . By dropping it by  20.1°F means there is a - 20.1°F  change in the temperature.

Then, the temperature at midnight = 16.8°F + (- 20.1°F)

= -3.3°F
