Question

HELP!!! A,B,or C

Eric was rock climbing. At one point, he stopped and climbed straight down 2 1/2 meters. Then he climbed straight up 6 3/4 meters.Eric was wondering what his change in elevation was after these two moves.

Answer 1

The answer is B
Let’s think of his current location as 0
Since he climbed down 2 1/2 meters, u would think of it as 0 - 2 1/2 which equals - 2 1/2
Now his current location is - 2 1/2
Then he goes up 6 3/4 so to get his new location, we would simply add 6 3/4 to -2 1/2
So the answer would be -2 1/2 + 6 3/4 which would be B! Hope this helps!!
