24.9%

Explanation:

In this question, we are asked to calculate the annual that would have been earned if a comic book bought in 1963 is sold in 2021.

We proceed as follows:

Price of comic book in 1963 = $0.14 or 14 cents

Price of comic book in 2021 = $55,700

The investment period = 58 years

We represent the rate of interest earned by buying the book in 1963 and selling in 2021 as r.

The Total amount A = P (1+r) ^n

55,700 = 0.14 (1+r) ^58

397,867 = (1+r) ^58

By computation,

1+r = 1.249

r = 0.249

This means that the rate of interest earned is 24.9%
