To return to the initial temperature of 64℉, we need to calculate the net change in temperature after the original drop and rise. Let's break it down step-by-step:
1. The temperature dropped 7℉. So, from 64℉, it went down to 64℉ - 7℉ = 57℉.
2. Next, the temperature rose by 11℉. So, from 57℉, it increased to 57℉ + 11℉ = 68℉.
Therefore, the temperature needs to fall by 4℉ to return to the initial temperature of 64℉.
So, the correct response is: Fall 4℉.
To solve this problem, we need to consider the change in temperature and find out how much it needs to rise or fall to return to the initial temperature of 64℉.
Given that the temperature dropped 7℉ and then rose 11℉, we can calculate the net change in temperature as follows:
Change in temperature = drop + rise
Change in temperature = -7℉ + 11℉
Change in temperature = 4℉
Since the temperature needs to return to the initial value of 64℉, we need to determine whether it should rise or fall to reach this value.
If the temperature needs to fall by 4℉, then the correct answer would be "Fall 4℉."
If the temperature needs to rise by 4℉, then the correct answer would be "Rise 4℉."
So, based on the information given, the possible correct answers are:
Fall 4℉
Rise 4℉
