Answer:

The correct option is D. -17.5 degrees

Step-by-step explanation:

The daytime temperature in Apple Valley is falling by 2.5 degrees each day

Therefore, Change in the temperature each day = -2.5 degrees

Now, we need to find the net change in the daily temperature after one calendar week

Now, number of days in one calendar week = 7

So, Net change in the daily temperature after one calendar week = Daily change × Number of days in one calendar week

⇒  Net change in the daily temperature after one calendar week = -2.5 × 7

⇒  Net change in the daily temperature after one calendar week = -17.5 degrees

Therefore, The correct option is D. -17.5 degrees
