Bingel [31]

The sale price after both markdowns will be $336

<em><u>Explanation</u></em>

The selling price of an item is $600. After 6 months of not selling, it is marked down by 30%

So, the marked down amount after 6 months $=\$ 600*0.30= \$180$

and the selling price after first 6 months will be: $\$600-\$180=\$420$

After another 6 months of not selling , it is further marked down by 20%. So, the marked down amount now $= \$420*0.20=\$84$

Thus, the final selling price after all markdowns $=\$420-\$84=\$336$
