C
Step-by-step explanation:
Method A:
270 decrease 25% =
270 × (1 - 25%) = 270 × (1 - 0.25) = 202.5
202.5 increase 6% =
202.5 × (1 + 6%) = 202.5 × (1 + 0.06) = 214.65
Method B:
270 increase 6% =
270 × (1 + 6%) = 270 × (1 + 0.06) = 286.2
286.2 decrease 25% =
286.2 × (1 - 25%) = 286.2 × (1 - 0.25) = 214.65
