How many years will it take you to double your money if; round off your answers to one decimal place. 1) your roi or rate of return is 4%? years. 2) your roi is 10%? years. 3) your roi is 13%? years.

Assuming the return is compounded annually, the multiplier each year for rate "r" is (1+r). Then the multiplier for "t" years is (1+r)^t. We want this to be 2.

... 2 = (1+r)^t

... log(2) - t·log(1+r)

... log(2)/log(1+r) = t

The attachment shows the rounded calculator result for r={4%, 10%, 13%}.

2? if not the correct answer you might need to provide more information
