Interpret the outcomes as final amounts received after the event.

EV(final) = 0.2·0 + 0.8·27,675 = 0.8·27,675 = 22,140.

So the expected value of investing is $22,140. Relative to the $10,000 you started with, the expected profit is 22,140 − 10,000 = $12,140. (Keeping the money in the bank would give $10,000, so investing has a higher expected return.)
