So let's see here ...

6:00 A. M. temperature is 33°F.

12:00 P. M temperature increased by 10°F making it 43°F.

3:00 P. M. temperature increased by another 12°F making it 55°F.

At 10:00 P. M it would decrease by 15°F making it 40°F.

The temperature would need to fall (or decrease) by 7°F to reach the original temperature of 33°F.
