To organize: the price per unit of each tire in a matrix B .
Answer to Problem 127RE
AB is not possible.
Explanation of Solution
Given information :
A tire corporation has three factories, each of which manufactures two models of tires.
The production levels are represented by A.
It is given that price per unit for a model A tire is $99 and the price per unit for a model B tire is $112.
Matrix B is represented as
In the above matrix, column 1 represents price per unit of model A tire and column 2 represents price per unit of model B tire.
To find: the product BA and interpret the result.
Answer to Problem 127RE
Explanation of Solution
Given information :
A tire corporation has three factories, each of which manufactures two models of tires.
The production levels are represented by A.
It is given that price per unit for a model A tire is $99 and the price per unit for a model B tire is $112.
So,
The matrix BA represents the total sum of cost of producing tires. The column 1 represents the total cost if the tires are produced from factory 1. Similarly, column2 and column 3 represents the total cost if the tires are produced from factory 2 and 3 respectively.
