#-7^@F##/#day

Explanation:

If the temperature dropped from #75^@F# to #40^@F# at a constant rate over a period of five days, if you find the range of the temperatures and divide the difference by #5# (the number of days the temperature dropped for), you will find the daily temperature change.

Thus, start by calculating the difference between #75^@F# and #40^@F#.

#75-40#

#=35#

Divide #35# by #5#, the total number of days the temperature dropped for.

#35-:5#

#=7#

#:.#, the daily temperature change was #-7^@F# per day.
