<u>The marked price of the article was $7865</u>
Answer:
solution given:
let marked price be x=?
discount =20%
vat=13%
selling price =$7232
we have
<u>discount amount=discount % of marked price</u>=20/100*x=0.2 x
and
<u>vat amount = vat% of selling price</u>=13/100*$7232=$940.16
we have
<u>Selling price with tax =marked price - discount amount + vat amount</u>
$7232=x-0.2x+$940.16
$7232-$940.16=x-0.2x
0.8x=$6291.84
x=$6291.84/0.8
x=<u>$7864.8</u>
