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?
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}.
