To find out how much the temperature needs to rise or fall to return to 71℉, we need to consider the net change in temperature.
Initially, the temperature was 64℉.
The temperature then dropped 7℉, so the new temperature is 64℉ - 7℉ = 57℉.
The temperature then rose 11℉, so the final temperature is 57℉ + 11℉ = 68℉.
To return to the initial temperature of 71℉, the temperature needs to rise by 71℉ - 68℉ = 3℉.
Therefore, the correct response is "Rise 3℉."
To find out how much the temperature needs to rise or fall to return to the initial temperature of 71℉, we need to calculate the difference between the current temperature and the initial temperature.
Given that the initial temperature was 64℉, the temperature dropped 7℉, so the current temperature is 64℉ - 7℉ = 57℉.
Then, the temperature rose 11℉, so the current temperature is 57℉ + 11℉ = 68℉.
To return to the initial temperature of 71℉, we need to calculate the difference between 68℉ and 71℉.
71℉ - 68℉ = 3℉.
Therefore, the temperature needs to rise 3℉ to return to the initial temperature of 71℉.
So the correct answer is: Rise 3℉.
To determine how much the temperature needs to rise or fall to return to the initial temperature of 71℉, we can calculate the net change in temperature.
Given that the initial temperature was 64℉ and it dropped 7℉, the temperature after the drop will be 64℉ - 7℉ = 57℉.
Then, the temperature rose 11℉ from 57℉, resulting in a final temperature of 57℉ + 11℉ = 68℉.
To return to the initial temperature of 71℉, the temperature needs to rise by an additional 71℉ - 68℉ = 3℉.
Therefore, the correct answer is: Rise 3℉.
