Final answer:
To determine the target cost for model J20, subtract the product cost from the target selling price and divide by 1 plus the markup percentage. The target cost is then $296.80.
Step-by-step explanation:
To determine the target cost for model J20, we need to calculate the target selling price. We know that the current selling price is $450 and engineers estimate that the competitive selling price for similar printers will be $430 next year. To maintain the historical markup percentage on product cost, we can subtract the product cost from the target selling price and divide by 1 plus the markup percentage. The product cost is $360, so the markup percentage is ($430 - $360) / $360 = 19.44%. The target cost is then $360 / (1+0.1944) = $296.80.
