We can use the exponential growth function as follows:
[tex]y=a(1+r)^t[/tex]Where:
a = Initial amount = 28300
r = Growth rate = 7% = 0.07
t = time ( in years)
so:
[tex]\begin{gathered} y=28300(1+0.07)^t \\ y=28300(1.07)^t \\ \end{gathered}[/tex]Evaluate the function for 17 years:
[tex]\begin{gathered} t=17 \\ y=28300(1.07)^{17} \\ y\approx89394 \end{gathered}[/tex]Answer:
Approximately 89394
