Write the rule of 70 . Suppose that your great-great-grandmother put $50 in a savings account 100 years ago and the account is now worth $1,600 . Use the rule of 70 to determine about what interest rate she earned


$1,600/$50 = 32 . The rule of 70 says that if X is the growth rate of a variable, then the variable doubles every 70/X years. This implies the value of the stock doubled five times. Since it doubled 5 times in 100 years, it doubled every 20 years. According to the rule of 70, the value of an asset doubles every 70/X years. So, we need 70/X = 20, which means that X is 3.5 percent.
