Q3

A company purchases x kilograms of steel for \$2249.52. The company processes the steel and turns it into parts that can be used in other factories. After this process, the total mass of the steel has dropped by 25 kg (due to trimmings, scrap, and so on), but the value of the steel has increased to \$ 10, 838.52. The company has made a profit of \\$2/kg. What was the original mass of the steel? What its the original cost per kilogram?
