Simple interest formula (not compound interest formula) is used here, as much as i know.
the formula is:
f = p * (1 + r * n).
f is the future value
p is the present value
r is the interest rate per time period
n is the number of time periods
Given
[tex]\begin{gathered} P=27000 \\ r=1.5\%=\frac{1.5}{100}=0.015 \\ n=3years \end{gathered}[/tex]Therefore, we have
[tex]f=27000(1+0.015\times3)=\text{ \$}28215[/tex]Hence, the answer is
[tex]\begin{equation*} \text{\$}28215 \end{equation*}[/tex]
