Since Eric climbed straight down 2 and 1/2 meters and then climbed straight up 6 and 3/4 meters, his change in elevation is the difference between the two distances. Thus, the equation that matches the situation is:
\[2\dfrac{1}{2} - 6\dfrac{3}{4} = ?\]
The correct answer is (Choice B).
\[2\dfrac{1}{2} - 6\dfrac{3}{4} = ?\]
The correct answer is (Choice B).
