C. What was the temperature at midnight?
Let x be the temperature at midnight.
According to the problem, the temperature rose 8°C from midnight to 6:00 am. So at 6:00 am, the temperature was x + 8°C.
We also know that at 6:00 am, the temperature was −20°C. So we can set up the equation:
x + 8 = −20
Solving for x:
x = −28
Therefore, the temperature at midnight was −28°C.
