She can burn up to 25 more calories than 280, or as little as 25 less calories than 280. The absolute difference is 25 calories.
Let x be the max/minimum amount of calories burnt in the day.
∣ x - 280 ∣ = 25
x - 280 = 25 or x - 280 = -25
x = 25 + 280 or x = -25 + 280
x = 345 (maximum) or x = 255 (minimum)
