- A rule exists, the so-called Rule of 72, for quickly estimating the number of years required for an investment to double. The equation can be expressed as n double = 72/i, where i is expressed as a percent (i.e., 10% would be expressed as 10). Develop a plot of time versus interest to double your investment. Overlay the actual formula, 2 = 1*(1+i)n, and comment on the accuracy of this rule.
