Final answer:
To calculate the rate of markup based on cost, subtract the cost price from the selling price to find the markup, then divide the markup by the cost price and multiply by 100 to get the percentage. The rate of markup for the serving tray is approximately 39.10%.
Step-by-step explanation:
The question requires us to calculate the rate of markup based on the cost of a serving tray.
First, we need to determine the amount of markup by subtracting the cost price from the selling price.
Markup = Selling Price - Cost Price = $2,010 - $1,445 = $565
Next, we calculate the rate of markup by dividing the markup by the cost price and then multiplying by 100 to get a percentage.
Rate of Markup = (Markup / Cost Price) × 100 = ($565 / $1,445) × 100
By calculating this, we find that the rate of markup based on cost is approximately 39.10%.
