  • How do the credit card companies make so much money?
    • Pretty straight forward: #6, p. 678
    • Here's a twist: #11, p. 679

    • Here's another straight-forward mortgage problem: #16, p. 680

  • A "real-world" example: do you use those balance-transfer checks? I got this offer last week.
    • What are the hidden costs (buried in the fine print)?
    • What would $1000 cost me for a year, if I take it out May 1, and pay nothing back? (By the way, the balance transfer APR is 18.99%).
