34. A company makes three different size tennis rackets. A small racket requires 1 unit of string, 2 units of rubber, and 3 units of titanium. A medium racket requires 2 units of string, 3 units of rubber, and 4 units of titanium. A large racket requires 3 units of string, 4 units of rubber, and 5 units of titanium. Each unit of string costs $1 . 50, each unit of rubber costs $2 . 25, and each unit of titanium costs $1 . 75. For a particular order, 200 small rackets, 150 medium rackets, and 80 large rackets are requested. Management has decided that Factory A will produce 150 of the small rackets, 50 of the medium rackets, and 60 of the large rackets. The remaining rackets of each size will be produced at Factory B. Put the above information into three matrices and then determine what matrix operation will tell you the cost of filling the order at each factory.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
