  12. Ch. 10 Economics • In a 30 day month option 1 wins • Option 1: $7.5 million • Option 2: $5.37 million (the doubling to $10.74 million would not be in effect in a 30 day month)

  15. Ch. 10 Economics • The “rule of 72” is shown on fig. 10.10. Using this rule you can calculate how long it will take a saved or invested sum of money to double at various interest rates by dividing the number 72 by the interest rate. Calculate how long it would take the sum of $500.00 to double at the interest rate of 18%.

  17. Ch. 10 Economics • Answers: • 1) 72 / 5 = 14.4 years • 2) 72 / 13 = 5.5 years • Always divide 72 by the rate of interest. “Rule of 72”
