The variation is at most 45. Let's she burned 30 calories more than 450. She burned 480. What is the variation from 480 to 450?

In this case the variation is 480 - 450 = 30 Notice you find the variation by subtracting, not adding. Choice B has an addition inside the absolute value, so it is not the answer. Also, notice that to find the variation, you need to subtract c - 450 and take the absolute value.

That points to this: \(|c - 450| \le 45\)
