A quote covers 14 units whose cost is $72 each. The target gross margin on the undiscounted selling price is 20%, so price = cost ÷ (1 − margin/100). Then apply a 11% customer discount to goods only and add $36 order freight. Tax is excluded. Margin is measured against selling price; markup would use cost.
Calculate the customer discount value in dollars. Keep intermediate values unrounded; round the final answer to 2 decimal places if needed.
