Answer:

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
