step1: Write out the formula for exponential growth


y=a(1+r)^n
\begin{gathered} a=\text{initial population} \\ r=\text{rate} \\ n=\text{years} \end{gathered}

Hence we have


a=800,r=3\text{ \%, n=x}

Step2: substitute into the formula in step 1


\begin{gathered} y=800(1+(3)/(100))^x \\ y=800(1+0.03)^x \\ y=800(1.03)^x \end{gathered}

Hence the right option is A
