Question

1. the rule of 72 is used to estimate:

a. the annual percentage yield of a bond
b. the approximate time it takes for an investment to double in value
c. the tax rate on investment income
d. the minimum balance required to avoid fees

Explanation:

The Rule of 72 is a financial concept. It states that to estimate the number of years required to double an investment at a given annual rate of return, you divide 72 by the annual interest rate (percentage). So it's used to find the approximate time for an investment to double. Option A is about bond yield calculation (not Rule of 72), C is about tax rates (unrelated), D is about minimum balances (unrelated).

Answer:

B. The approximate time it takes for an investment to double in value
