I need help solving these types of problems here is one one of them. Can somone show me how to solve them.thanks

Production Requirements 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 the following amounts of materials?
a. 810 units of copper, 410 units of zinc, and 490 units of glass
b. 765 units of copper, 385 units of zinc, and 470 units of glass
c. 1010 units of copper, 500 units of zinc, and 610 units of glass

a. Consider how many transistors can be made, sith Copper:Glass:Zinc in a 3:2:1 ratio.

There clearly is an excess of zinc. The limiting ingredient is glass since the 810 units of copper would require 540 of glas, and there is not that much available. Using 490 units of glass, you require 245 units of zinc (1/2 x 490) and 735 units of copper (3/2 x 490)

Do the others similarly
