An electronics company produces transistors, resistors, and computer chips. Each transistor consists of 3 units of copper, 1 unit of zinc, 2 units of glass. Each resistor consists of 3,2, and 1 of the 3 materials and each computer chip consists of 2, 1, and 2 of the materials. How many of each can be made with 2050 units of copper, 915 units of zinc, and 13-5 units of glass? Use the inverse of the co-efficient matrix to solve the equation.
