Given:

[tex]\begin{gathered} In\text{ 2003, the price was \$}16,500 \\ In\text{ 2021, the price was \$}17,300 \end{gathered}[/tex]

The increase in price from 2003 to 2021 is;

[tex]\begin{gathered} Increase=17300-16500 \\ Increase=\text{ \$}800 \end{gathered}[/tex]

The percent increase is gotten by;

[tex]\begin{gathered} Percent\text{ increase}=\frac{increase}{initial\text{ value}}\times100\text{ \%} \\ Percent\text{ increase}=\frac{800}{16500}\times100\text{ \%} \\ Percent\text{ increase}=4.848484848484 \\ Percent\text{ increase}\approx4.85\text{ \%} \end{gathered}[/tex]

Therefore, the percent increase is approximately 4.85%
