Tim is working on a school report on the proposed merger between American Airlines and U.S. Airways. He finds that U.S. Airways’ annual revenue for 2012 rose by 3.7 percent over the previous year, while the revenue for American Airlines recorded an increase of almost 6 percent. Based on this, he concludes that, in 2012, passenger traffic must have increased more for American Airlines than for U.S. Airways. Is Tim’s conclusion correct? Explain your answer.
