Greetings!

We can solve this by creating an algebraic equation.
[tex]3d+d=600[/tex]
[tex]d=dryer[/tex]

Solve for d.
[tex]4d=600[/tex]
Divide both sides by 4.
[tex](4d)/4=(600)/4[/tex]
The Answer Is:
[tex]d=150[/tex]

To Check:
[tex]w+150=600[/tex]
Add -150 to both sides.
[tex](w+150)+(-150)=(600)+(-150)[/tex]
[tex]w=450[/tex]
[tex]150*3=450[/tex]

The Dryer cost $150.

Hope this helps.
