How much did each boy make on their investment (write in words, not numbers)? Which strategy is best? Why? (5 points) Believe it or not, Ben came out ahead . . . $700,000 ahead! Arthur had a total of $1,532,166 while Ben had a total of $2,288,996. How did he do it? Starting early is the key. He put in less money but started eight years earlier. That’s compound interest for you! It turns $16,000 into almost $2.3 million! Since Ben invested earlier, the interest kicked in sooner.
