A manufacturer makes two type if products X and z at each if two different locations A and B. the materials used to make each if
Snezhnost [94]

Using matrix algebra, the material cost of making one of each product at each location is as follows:​

<h3 />

                       Product X    Product Z

Location A        birr 38          birr 50

Location B        birr 38          birr 49.5

<h3>What is matrix algebra?</h3>

Matrix algebra involves the arrangement of numbers in a rectangular array.

Matrices are arranged in columns and rows to express some mathematical values.

<h3>Data and Calculations:</h3><h3>Matrix O: Materials Requirement Per Unit</h3>

                      Steel    Glass    Plastic

Product X         3            1             2

Product Z         4          0.5           3

<h3>Matrix P: Materials Cost Per Unit</h3>

                      Steel    Glass    Plastic

Location A      10           2           3

Location B       9           3           4

<h3>Matrix R: (O x P) Material Cost of Product X</h3>

                      Steel    Glass    Plastic   Total

Location A     30           2           6          38

Location B     27           3           8          38

<h3>Matrix R: (O x P) Material Cost of Product Z</h3>

                      Steel    Glass    Plastic   Total

Location A     40          1             9          50

Location B     36          1.5         12         49.5

Thus, Product X costs birr 38 at locations A and B, respectively, while Product Z costs birr 50 and birr 49.5 at locations A and B, respectively.
