To find out how much the temperature needs to change to return to the initial temperature of 63°F, we can follow these steps:
-
Start with the initial temperature: \(63°F\)
-
The temperature drops by 10°F: \[ 63°F - 10°F = 53°F \]
-
The temperature then rises by 6°F: \[ 53°F + 6°F = 59°F \]
Now, we need to determine how much the temperature needs to change from 59°F to return to 63°F:
\[ 63°F - 59°F = 4°F \]
Since we need to rise to get back to 63°F, the answer is:
Rise 4°F.
