The selling price of an item is $455. It is marked down by 20%, but this sale price is still marked up from a cost of $280. Find the markup from the cost to sale price.

$84

Explanation:

Calculation to Find the markup from the cost to sale price

Using this formula

Cost to sale price markup=[Selling price-(Marked down percentage *Selling price)]- Sale price marked up

Let plug in the formula

Cost to sale price markup=[$455-(20%*$455)]-$280

Cost to sale price markup=($455-$91)-$280

Cost to sale price markup=$364-$280

Cost to sale price markup=$84

Therefore the markup from the cost to sale price will be $84
