Given that the initial price of the car is;
[tex]25,000[/tex]And after one year the price decreased to;
[tex]20,000[/tex]The percentage change in the price will be;
[tex]\begin{gathered} \text{ \%P }=\frac{25000-20000}{25000}\times100\text{\%} \\ \text{ \%P }=\frac{5000}{25000}\times100\text{\%} \\ \text{ \%P }=0.2\times100\text{\%} \\ \text{ \%P }=20\text{\%} \end{gathered}[/tex]Therefore, the percentage decrease in the value of the car is;
