Final answer:
Markup is 66.67%, the discounted price after 25% off is $15, but the additional employee discount cannot be calculated without the discount percentage.
Step-by-step explanation:
The question involves calculating percent markup, the discounted price, and the price after an additional employee discount.
Percent Markup Calculation
To calculate the percent markup, you subtract the cost to manufacture from the selling price and then divide by the cost to manufacture. Finally, multiply by 100 to get a percentage.
Percent Markup = ((Selling Price - Cost to Manufacture) / Cost to Manufacture) * 100
Percent Markup = (($20 - $12) / $12) * 100 = (8 / 12) * 100 = 66.67%
Discounted Price Calculation
The discount is 25% off of the $20 selling price, so:
Discounted Price = Selling Price - (Selling Price * Discount Percentage)
Discounted Price = $20 - ($20 * 0.25) = $20 - $5 = $15
Price After Employee Discount
If you also have an employee discount, you would apply it to the discounted price. However, the employee discount percentage is not provided in the question, so we cannot calculate the final price without it.
