The final value of an investment P in a bank at a compound interest of rate r for t years is given by:


$$FV=P(1+(r)/(m))^(m\cdot t)$$

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)

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
