Fall 4℉
Rise 3℉
Fall 7℉
Rise 11℉
Fall 4℉
To find out how much the temperature needs to rise or fall to return to the initial temperature of 64℉, we need to calculate the net change in temperature.
Given:
Initial temperature = 64℉
Temperature dropped = 7℉
Temperature rose = 11℉
To calculate the net change, we will subtract the temperature dropped from the temperature rose:
Net change = Temperature rose - Temperature dropped
Net change = 11℉ - 7℉
Net change = 4℉
Since the net change is the difference between the temperature rose and the temperature dropped, the temperature needs to fall by 4℉ to return to the initial temperature of 64℉.
Therefore, the correct answer is "Fall 4℉."
To determine how much the temperature needs to rise or fall to return to the initial temperature of 64℉, we need to consider the total change in temperature.
First, the temperature dropped 7℉. So, the current temperature is 64℉ - 7℉ = 57℉.
Next, the temperature rose 11℉. So, the current temperature is 57℉ + 11℉ = 68℉.
Finally, to return to the initial temperature of 64℉, the temperature needs to fall by 68℉ - 64℉ = 4℉.
Therefore, the temperature needs to fall by 4℉ to return to the initial temperature of 64℉. So, the answer is "Fall 4℉".
