Present value (PV) = $100,000

Number of years (n) = 12 years

Future value (FV) = $240,000

FV = PV (1 + r) n

$240,000 = $100,000 (1 + r) 12

$240,000 = (1 + r) 12

$100,000

2.4 = (1 + r) 12

12√2.4 = 1 + r

1.0757 - 1 = r

0.0757 = r

r = 0.0757 = 7.57% = 8%

Explanation:

In this case, we need to apply the formula for future value of a lump sum (single investment). The present value, future value and number of years have been provided in the question with the exception of interest rate. Thus, interest rate becomes the subject of the formula, which implies that we will solve for interest rate.
