The volume of a raw material required for a certain machine part is 2.02 cu. cm. The finished volume is 1.05 cu. cm. The time for machining each piece is 45 seconds for steel and 30 seconds for brass. The cost of steel is P32.50 per kg and the value of steel scrap is negligible. The cost of the brass is P60.00 per kg and the value of brass scrap is P25.00 per kg. The wage of the operator is P40.00 per hour and the overhead cost of the machine is P50.00 per hour. The weight of steel and brass are 0.0081 and 0.0088 kg per cu. cm., respectively. Which material will you recommend?
