The temperature outside changed from 85°F to 43°F over a period of six days. If the temperature changed by the same amount each day, what was the daily temperature change?
1 answer
To find the daily temperature change, we subtract the initial temperature from the final temperature and then divide that difference by the number of days. 43°F - 85°F = <<43-85=-42>>-42°F. Since the temperature changed by this amount over 6 days, the daily temperature change is -42°F/6 = <<-42/6=-7>>-7°F per day. Answer: \boxed{-7}.
