The compound interest formula is:
![A=P(1+(r)/(n))^(nt)](https://img.qammunity.org/2023/formulas/mathematics/high-school/39foo2gerf9tf1ffk32zwshrn339mz02kv.png)
where A is the final amount, P is the principal, r is the annual interest rate (as a decimal), n is the number of times interest is compounded per year, and t is time in years.
Substituting with P = $41.67, r = 0.045 (=4.5/100), n = 365 (the interest is compounded daily), and t = 3 years, we get:
![\begin{gathered} A=41.67(1+(0.045)/(365))^(365\cdot3) \\ A=41.67(1.00012)^(1095) \\ A=47.69\text{ \$} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/tjd3ea9axauf3xgozxyzzx1xpj9iiixpx0.png)
