The temperature in Antarctica at noon is 14°F. By 9:00PM, the temperature had dropped by 16.2 degrees. What was the temperature at 9:00PM?

Question

A –2.2°F
B 2.2°F
C –30.2°F
D 30.2°F

Answer 1

To find the temperature at 9:00 PM, we need to subtract the temperature drop of 16.2 degrees from the temperature at noon.

Temperature at 9:00 PM = Temperature at noon - Temperature drop
Temperature at 9:00 PM = 14°F - 16.2°F

This gives us a negative value, so we need to subtract a negative, which is the same as adding a positive.

Temperature at 9:00 PM = 14°F + 16.2°F
Temperature at 9:00 PM = 30.2°F

Therefore, the temperature at 9:00 PM in Antarctica was 30.2°F.

The correct answer is D) 30.2°F.
