Respuesta :

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
