Question

Suppose an investment of $10,000 doubles in value every 13 years. How much is the investment worth after 52 years? After 65 years?

A: $80,000; $100,000

B: $160,000; $320,000

C: $520,000; $650,000

Answer 1

Explanation:

The answer is actually B. $160,000; $320,000

The reason for this is because -

$10,000 is the constant, so let a= 10,000.

The investment doubles every 13 years, so let b=2.

Let x= the number of 13-year periods.
