QUESTION 7 (Not a repeat of other questions about this industry.) Concrete blocks used in the construction industry start as cement and sand purchased by a manufacturer who transforms them into blocks of different sizes and shapes. Assume the following information exists for the value chain of concrete block industry. (All data is per palette; a palette contains 50 square feet of blocks.) Manufacturers Wholesalers Retailers Sales $37.50 $70.00 $100.00 Value of goods/services acquired from 11.75 70.00 outside 37.50 Value added by the firm 22.00 15.00 25.00 Total Cost 33.75 52.50 95.00 Profit $3.75 $17.50 $5.00 ROS 10.00% 25.00% 5.00% Markup on cost 111.11% 133.33% 105.26% The basic raw materials for concrete block, cement and sand, have been marked up several times in the conversion process through the value chain. An average customer pays nearly: CA. Cannot be computed from the information provided C B. Nearly 851% more for the blocks compared to the original raw material cost C. Nearly 105.26% more for the blocks compared to the original raw material cost D. Nearly 30% more for the blocks compared to the original raw material cost CE. Nearly 35% more for the blocks compared to the original raw material cost
