Let the original price of the car be x
Three times its original price will be
[tex]3\times x=3x[/tex]$2500 less than three times it original price will be
[tex]3x-2500[/tex]If the selling price is now $14000, then we can say;
[tex]3x-2500=14000[/tex]Solve the equation above to obtain the value of x, the original price of the car
[tex]\begin{gathered} 3x-2500=14000 \\ 3x=14000+2500 \\ 3x=16500 \\ \frac{3x}{3}=\frac{16500}{3} \\ x=5500 \end{gathered}[/tex]Hence, the original price of the car is 5500
