Give the step-by-step reasoning process and then the final answer. John buys 4 pounds of beef. He uses all but 1 pound in soup. He uses twice as many pounds of vegetables as beef. How many pounds of vegetables did he use?
He used 4 - 1 = 3 pounds of beef. So he used 3 * 2 = 6 pounds of vegetables.
The final answer: 6.
