Answer:

A) $ 520

B) $ 540.8

C) $ 562.432

Step-by-step explanation:

Since, the amount formula in compound interest calculated annually,

[tex]A=P(1+r)^t[/tex]

Where,

P = principal amount,

r = annual interest rate,

t = number of years,

A) P = $ 500, r = 4% = 0.04, t = 1,

[tex]A=500(1+0.04)^1 = 500(1.04)=\$ 520[/tex]

B) P = $ 520, r = 0.04, t = 1,

[tex]A=520(1+0.04)=520(1.04)=\$ 540.8[/tex]

C) P = $ 540.8, r = 0.04, t = 1,

[tex]A=540.8(1+0.04)=540.8(1.04)=\$ 562.432[/tex]
