Jane improved her test score by 40% the second time she took it. If she answered 200 questions correct in her last test, how many questions did she correctly answer this time?
If her score is 40% higher than her last score of 200 correct questions, then she got 80 questions more correct (200 x 0.4) or (200 x 4/10). 200 + 80 = 280 questions. OR 200 x 1.40 = 280
