By September 2016, 53 years later, given the condition it's in, the value of this comic book had risen to $14 comma 500. What annual rate of interest would you have earned if you had bought the comic in 1963 and sold it in 2016?

r = 24.71%

purchase the comin in 1963 and selling in 2016 will achieve a 24.71% return on investment

Explanation:

the original value was 0.12

then after 53 years the future value is 14,500

We need to solve for the rate at which that nominal amount becomes a future value of 14,500 dollars in 53 years:

r = 0.247068519

r = 24.71%
