Final answer:
To find the discount price of a desk lamp from the wholesale cost of $14 with a markup of 45 percent and a markdown of 20 percent, you first calculate the selling price to be $20.30. Then apply the markdown to get the final discount price of $16.24.
Step-by-step explanation:
To calculate the discount price for desk lamps at your office supply store, we need to first determine the selling or retail price by marking up the wholesale cost by 45 percent. Then, we apply a markdown of 20 percent on that selling price to find the discounted price.
The markup on the wholesale price is calculated as follows:
(Markup percentage) × (Wholesale cost) = Markup amount
0.45 × $14 = $6.30
The selling price before the discount would therefore be:
(Wholesale cost) + (Markup amount) = Selling price
$14 + $6.30 = $20.30
To calculate the discount price after marking down the selling price by 20 percent:
(Markdown percentage) × (Selling price) = Markdown amount
0.20 × $20.30 = $4.06
The discount price of the desk lamps is:
(Selling price) - (Markdown amount) = Discount price
$20.30 - $4.06 = $16.24
