Please solve in detail when you reach the cost of the product per unit

Section Two: Product Pricing and Performance Metrics Mr. Khaled, The general manager of the company, was impressed by your experience as the financial comptroller. He has requested to meet with you to discuss the new selling prices for each of the company products based on your report on the unit cost under the new costing system (see Section 1). Write your recommendations in detail to Mr. Khaled assuming that he is considering selling the company products to the market at the "cost plus 20% profit margin". You have been informed that the invested capital is $5,500,000 for each of the goalkeeper's gloves and goal nets, and $2,500,000 for each of the training equipments and the traditional footballs. The required 15% return on investment for all products has been reached. The general manager has asked to increase the price by 2% and to allocate that amount for product development as they are planning to bring in new machines that possess technological capabilities while helping to preserve the sustainable environment. Mr. Khalid has also informed you that all units produced are expected to be sold by the end of this year. Based on the abovementioned information, you have been asked to help Mr. Khalid to set the target prices for each of the four products. Required: (a) Calculate the target prices that should be charged to each product according to the proposed pricing plan, knowing that the company has started to adopt the activity-based costing method to determine the cost per unit. (20%) (b) Calculate the profit margin as a percentage of the total cost of each product. (5\%) (c) Calculate profit as a percentage of sales (i.e. return on sales). Which of the two performance measures (i.e profit as a percentage of cost, or profit as a percentage of sales) is better for the company as a basis for evaluating products? Discuss the reason behind your choice. (5%)
