The final value of an investment P in a bank at a compound interest of rate r for t years is given by:
![$$FV=P(1+(r)/(m))^(m\cdot t)$$](https://img.qammunity.org/2023/formulas/mathematics/college/fjojvppkqmvcfyxs2bo47xl4ai5hr4inlb.png)
Where m is the number of compounding periods per year.
We are given:
P = $22,000
r = 3.2% = 3.2 / 100 = 0.032
t = 7 years
m = 12 (12 months in a year).
Applying the formula:
![FV=\$22,000(1+(0.032)/(12))^(12\cdot7)](https://img.qammunity.org/2023/formulas/mathematics/college/3utarniue2ezmv3vq8tp7o45n0awc3fmtg.png)
Calculating:
![\begin{gathered} FV=\$22,000(1.0026666)^(84) \\ \\ FV=\operatorname{\$}22,000(1.2507) \\ \\ FV=\$27,515 \end{gathered}]()
Ikaros will have $27,515 after 7 years
