-16.8 / 14 = - 1.2 per day

Answer: D. -1.2 Degree Fahrenheit.

Step-by-step explanation:

Since,

[tex]\text{ The average daily changes } =\frac{\text{ Total changes}}{\text{ Number of days}}[/tex]

Here,

The total changes = - 16.8° F ( - sign shows the decreasing )

And, the number of days = 14

Hence,

[tex]\text{ The average daily changes } =-\frac{16.8}{14}=-1.2[/tex]

⇒ The average daily rate of change in the high temperature in degrees Fahrenheit is -1.2° F.
