CorrectNot quiteAnswer B

Correct answer: B

The fall itself is $80{,}000 - 68{,}000 = 12{,}000$ .
A percentage change is always measured against the value you started from, so divide by 80,000, not by 68,000.
$\frac{12{,}000}{80{,}000} = 0.15$ , which is 15%.

Worth noting

Dividing by the new figure gives $\frac{12{,}000}{68{,}000} \approx 17.6\%$ . That number answers a different question: by what percentage the smaller figure would have to rise to get back.
