If the temperature is 22°C and it drops by 5 degrees, what is the new temperature?

• A. 15°C
• B. 18°C
• C. 16°C
• D. 17°C

Answer: (D)

Subtracting a decrease from the starting temperature. When something drops by 5 degrees, you subtract 5 from the original temperature. From 22°C, subtract 5 to get 17°C. So the new temperature is 17°C. This matches a 5-degree decrease; 22 − 5 equals 17. The other numbers would come from subtracting a different amount, not the 5-degree drop.
