Answer:
The new temperature will be -25 degrees.
Step-by-step explanation:
We need to determine the number of hours from 4 pm to 10 pm
That is 6 hours.
The temperature drops 3 degrees each hour, so 3*6 = 18
The temperature will drop 18 degrees.
The temperature starts at -17 degrees,
-17-18 = -25
The new temperature will be -25 degrees.
