Let the base price be x, cost of tow package be y and cost of hard be z.

So equation for three variables are,

[tex]x+y=24290[/tex][tex]x+y+z=25285[/tex][tex]x+z=24890[/tex]

Substract equation x + z = 24890 from equation x + y + z = 25285 to obtain the value of y.

[tex]\begin{gathered} x+y+z-(x+z)=25285-24890 \\ y=395 \end{gathered}[/tex]

Substract equation x + y = 24290 from x + y + z = 25285 to obtain the value of z.

[tex]\begin{gathered} x+y+z-(x+y)=25285-24290 \\ z=995 \end{gathered}[/tex]

Substitute the values in the equation x + y +z = 25285 to obtain the value of x.

[tex]\begin{gathered} x+395+995=25285 \\ x=25285-1390 \\ =23895 \end{gathered}[/tex]

So base price is $23895, cost of tow package is $395 and cost of hard top is $995.
