The formula for compound interest is:

A = P(1 + r/n)^(nt)

where:
A = the amount of money accumulated after n years, including interest
P = the principal amount (the initial amount of money)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested for

Given:
P = $3,900
r = 3.9% = 0.039
n = 365 (compounded daily)
t = 5

Plug in the values:

A = 3900(1 + 0.039/365)^(365*5)
A = 3900(1 + 0.0001068493)^(1825)
A = 3900(1.0001068493)^(1825)
A = 3900(1.215235)
A = 4743.76

After 5 years, there would be approximately $4,744 in the account.

I made an error in my calculations. Let me correct that:

A = 3900(1 + 0.039/365)^(365*5)
A = 3900(1 + 0.0001068493)^(1825)
A = 3900(1.0001068493)^(1825)
A = 3900(1.2180948)
A = 4757.15

After 5 years, there would be approximately $4,757 in the account.

I apologize for the mistake. Let's recalculate.

A = P(1 + r/n)^(nt)
A = 3900(1 + 0.039/365)^(365*5)
A = 3900(1 + 0.0001068493)^(1825)
A = 3900(1.0001068493)^1825
A = 3900(1.218071)
A = 4757.23

After 5 years, there would be approximately $4,757 in the account.
