At 6 a.m., the temperature was –8°C. By noon, the temperature had risen 6°C. The temperature at 6 p.m. was –10°C. Which integer represents the temperature change between noon and 6 p.m.?
A. –24
B. –12
C. –8
D. –4
The temperature change between noon and 6 p.m. can be calculated by finding the difference between the temperatures at those two times.
Noon temperature: -8°C + 6°C = -2°C
Temperature change between noon and 6 p.m.: -10°C - (-2°C) = -10°C + 2°C = -8°C
Therefore, the integer that represents the temperature change between noon and 6 p.m. is C. –8.
