A cement kiln with production capacity of 125 tons per day (24 hours) of clinker has at its burning zone about 42 tons of magnetite chrome bricks being replaced periodically, depending on some operational factors and the life of the bricks. If locally produced bricks cost P23,450 per ton and have a life of 6 months, while certain imported bricks costing P29,000 per ton and have a life of 7 months, determine the more economical bricks and by how much.
