The first step in solving this problem is to find the discount received from the wholesale dealer for cadi DVD player by multiplying the listed price by the discount percentage:
$80 x 0.25 = $20
Next, find the actual price per DVD player paid to the wholesale dealer:
$80-$20=560
Now find the retail margin by multiplying the markup percentage by the original wholesale price:
$80x0.20 = $16
Next, find the retail price for which the technology store sells the DVD players to its customers by adding the markup amount to the listed wholesale amount:
$80+ $16 = $96
To find the profit margin, subtract the retail price from the actual price paid to the wholesale dealer.
$96 $60 = $36 profit per DVD player
