Use the depreciation formula.
[tex]\sf p(1-r)^n[/tex]
Where 'p' is the principal value, 'r' is the rate it depreciates, and 'n' is the time. Just plug in what we know:
[tex]\sf 28000(1-0.0725)^5[/tex]
Simplify by subtracting:
[tex]\sf 28000(0.9275)^5[/tex]
Simplify the exponent:
[tex]\sf 28000(0.6864)[/tex]
Multiply:
[tex]\sf\approx\boxed{\sf\$ 19219.20}[/tex]
