Answer:
A. $54
B. 55.62
C. $70.46
Explanation:
The formula for calculating compound interest is
FV = P (1 + r ) ^n
FV = Future value
P = Present value
R = interest rate
N = number of years
A. $1,800 (1.03) = $1854
Interest rate = $1854 -$1,800 = $54
B. $1,800 (1.03)^2 = $1,909.62
Interest rate = $1,909.62 - $1854 = $55.62
C. $1,800 (1.03)^10 = $2,419.05
To service the interest rate, we have to determine the future value in year 9
$1,800 (1.03)^9 = $2,348.59
Interest rate = $2,419.05 - $2,348.59 = $70.46
