Ostrovityanka [42]

Answer:

$113.08

Step-by-step explanation:

The formula for calculating future value:

FV = P (1 + r/m)^mn

FV = Future value

P = Present value

R = interest rate

N = number of years

m = number of compounding

14,000(1.12)^2 = 17,561.60

14,000 ( 1 + 0.12/2)^(2x2) = 17674.68

Difference : 17674.68 - 17,561.60 = $113.08
