At 6 a.m., the temperature was -8ºc. by noon, the temperature had risen 6ºc. the temperature at 6p.m. was-10ºc. which integer represents the temperature change between noon and 6p.m.? a -24 b -12 c -8 d -4

First, we can solve -8+6, which equals -2 because we are told that between 6 a.m. and noon, the temperature rose 6 degrees. Then, we are told that the temperature is -10 at 6 p.m., which tells us that there was an 8 degree drop between noon and 6 p.m. So our answer is C since
-2 - 8 = -10.
