Answer:

$24.5

Step-by-step explanation:

Let x be the cost of sweater before markup.

We are told that Dan paid $34.30 for a sweater the price included a 40% markup. This means x plus 40% of x equals 34.30.

We can represent this information as:

[tex]x+\frac{40}{100}x=34.30[/tex]

[tex]x+0.40x=34.30[/tex]

[tex]1.40x=34.30[/tex]

[tex]x=\frac{34.30}{1.40}[/tex]

[tex]x=24.5[/tex]

Therefore, the cost of sweater before the markup was $24.5.
