Answer :

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.
