An electronics company produces transistors, resistors, and computer chips. each transistor requires 3 units of copper, 1 unit of zinc, and 2 units of glass. each resistor requires 3, 2, and 1 units of the three materials, and each computer chip requires 2, 1, and 2 units of these materials, respectively. how many of each product can be made with 2180 units of copper, 1110 units of zinc, and 1290 units of glass? solve this exercise by using the inverse of the coefficient matrix to solve a system of equations.
