. In Whitehorse, the high temperature for the day was 7°C,
and in Yellowknife the high for the same day was -8°C.
What was the difference in high temperatures between the
two cities?
A -5°C
8 -1°C
C 8°C
D
15°C

I believe the answer is D, 15.

Step-by-step explanation:

Here's why. When finding the difference between two numbers, you must use absolute values. The absolute value of -8 is 8, since it is 8 units AWAY from 0. Apply the same thing to seven and then add them up.

If you take 8+7 (both absolute values), you get 15.
