You can put this solution on YOUR website!
all you need to do is plug 13,000 in vor v and solve for t.
\r
\n" ); document.write( "\n" ); document.write( "13,000 = -3000t + 22,000 --> subtract 22,000 from both sides
\n" ); document.write( "-9,000 = -300t --> divide both sides by -300
\n" ); document.write( "30 = t
\r
\n" ); document.write( "\n" ); document.write( "so the car is 30 years old.
