Explanation Given information: The equation for doubling the investment is 2 = ( 1 + r 100 n ) n t where r is the percentage of interest and n is the number of times compounded per year. The investment is done at 7.2% compounded monthly. Formula used: According to the property of logarithmic functions, The logarithmic form a = log b y , can be converted into exponential form as b a = y . According to change of base formula, log b x = ln x ln b Calculation: Consider the provided equation 2 = ( 1 + r 100 n ) n t For the investment at 7.2% compounded monthly. Here r is 7.2 and n is 12. So, 2 = ( 1 + 7.2 100 ( 12 ) ) 12 t It implies that; 2 = ( 1.006 ) 12 t Use the property of logarithms to convert the exponential form in logarithmic form
