I = 1
II = 1 + 1 = 2
V = 5
VI = 5 + 1 = 6
IV = 5 - 1 = 4
X = 10
A. XVIII = 10 + 5 + 1 + 1 + 1 = 18
B. VII = 5 + 1 + 1 = 7
C. XXVII = 10 + 10 + 5 + 1 + 1 = 27
D. XVII = 10 + 5 + 1 + 1 = 17

<h3>The worth after 4 years is $ 680.24</h3>
<em><u>Solution:</u></em>
<em><u>The formula for compound interest, including principal sum, is:</u></em>

Where,
A = the future value of the investment
P = the principal investment amount
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per unit t
t = the time the money is invested
From given,
n = 1 ( since interest is compounded annually)
p = 500
t = 4

<em><u>Substituting the values we get,</u></em>

Thus the worth after 4 years is $ 680.24
