Question
Transcribed Image Text: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? Complete
parts (a) through (c) below.
(a) Let x represent the number of transistors that can be made, y the number of resistors, and z the number of computer chips. Write a system of three linear equations when the amounts of
available materials are 775 units of copper, 385 units of zinc, and 470 units of glass. Choose the correct answer below.
A. 3x + 3y + 2z = 385
x+2y+z=775
2x+y + 2z = 470
O C. 3x + 3y + 2z = 775
x + 2y + z = 385
2x+y + 2z = 470
The company can make 6 transistors, 2 resistors, and 3 computer chips.
(b) 770 units of copper, 380 units of zinc, and 490 units of glass
The company can make
transistors,
resistors, and
(c) 980 units of copper, 475 units of zinc, and 590 units of glass
The company can make
computer chips.
transistors, resistors, and computer chips.
O B. x+y+z= 385
2x+y+z=775
2x+y + 2z = 470
D. x+3y + 2z=470
3x + 3y + 2z = 385
x + 2y + z = 775
