Rob has 24 baseball cards, and a few are doubles. One third of Rob's cards are doubles, and Jess has 5 times as many doubles as Rob. How many doubles baseball cards does Jess have? Give me reasons, before answering the question

Rob has 24 / 3 = 8 doubles baseball cards. Jess has 8 * 5 = 40 doubles baseball cards. So the final answer is 40.
