Answer:
5°F
Step-by-step explanation:
In eight days, the temperature change Falls from 85°F to 45°F. That's a fall of 40°F i.e 85°-45°
The question therefore says, in the period of those 8 days, if the same amount of temperature change occurs, what is the change per day.
In 8 days, 40°F falls. How many temperature change per day. To get this, we would divide 40 by 8
40/8= 5
Each day, there's a 5°F fall in temperature change
