Let's break down the temperature changes step by step:
1. The initial temperature is 67 °F.
2. The temperature drops 6 °F:
\[
67 °F - 6 °F = 61 °F
\]
3. Then, the temperature rises 10 °F:
\[
61 °F + 10 °F = 71 °F
\]
Now, we need to find out how much the temperature must change to return to the initial temperature of 67 °F.
From the current temperature of 71 °F to return to 67 °F, we would need to fall:
\[
71 °F - 67 °F = 4 °F
\]
So, the temperature needs to **fall 4 °F** to return to the initial temperature of 67 °F.
The correct response is **Fall 4 °F**.
1. The initial temperature is 67 °F.
2. The temperature drops 6 °F:
\[
67 °F - 6 °F = 61 °F
\]
3. Then, the temperature rises 10 °F:
\[
61 °F + 10 °F = 71 °F
\]
Now, we need to find out how much the temperature must change to return to the initial temperature of 67 °F.
From the current temperature of 71 °F to return to 67 °F, we would need to fall:
\[
71 °F - 67 °F = 4 °F
\]
So, the temperature needs to **fall 4 °F** to return to the initial temperature of 67 °F.
The correct response is **Fall 4 °F**.
