To find out how much the temperature needs to rise or fall to return to the initial temperature of 71℉, we need to determine the net change in temperature.
Given that the initial temperature was 64℉ and it dropped 7℉, the temperature would be 64 - 7 = 57℉.
Next, the temperature rose by 11℉, so the new temperature would be 57 + 11 = 68℉.
To return to the initial temperature of 71℉, the temperature needs to rise by 71 - 68 = 3℉.
Therefore, the correct answer is "Rise 3℉".
To find out how much the temperature needs to rise or fall to return to the initial temperature of 71℉, let's break it down step-by-step:
1. Start with the initial temperature of 64℉.
2. The temperature then dropped 7℉, so subtract 7℉ from the initial temperature: 64℉ - 7℉ = 57℉.
3. The temperature then rose 11℉, so add 11℉ to the current temperature: 57℉ + 11℉ = 68℉.
4. To return to the initial temperature of 71℉, the temperature needs to rise by 3℉.
Therefore, the correct answer is: Rise 3℉.
