Yes, I agree with Sally's work
Step-by-step explanation:
Monday's temperature:
The initial temperature = -5°F
During the day, it increased by 20°F = +20°F
At night it reduced by 25°F = -25°F
The temperature change on Monday:
The temperature change on monday from calculation is -10°F
Sally got a temperature change of -10°F.
Hence, we do agree with Sally's work . As the temperature change was the same.
