Answer to Problem 83AYU
The matrices are
Explanation of Solution
Given information:
The number of credit hours taken and the cost per credit hour for Nikki and Joe who take classes at a community college, LCCC and a local university, SIUE is provided below,
Calculation:
Consider the number of credit hours taken and the cost per credit hour for Nikki and Joe who take classes at a community college, LCCC and a local university, SIUE is provided below,
Let matrix A that represent the credit hours taken by each student and matrix B that represent the cost per credit hour.
So, row 1 of matrix A denote the credit hours taken by Nikki at two universities. And row 2 of matrix A denote the credit hours taken by Joe at two universities. Matrix B will be a column
Therefore,
To calculate: The value of
Answer to Problem 83AYU
The value of
Explanation of Solution
Given information:
The number of credit hours taken and the cost per credit hour for Nikki and Joe who take classes at a community college, LCCC and a local university, SIUE is provided below,
Formula used:
To find the product AB of two matrices A and B, the number of column in matrix A must be equal to number of rows in matrixB.
Calculation:
Consider the number of credit hours taken and the cost per credit hour for Nikki and Joe who take classes at a community college, LCCC and a local university, SIUE is provided below,
Let matrix A that represent the credit hours taken by each student and matrix B that represent the cost per credit hour.
So, row 1 of matrix A denote the credit hours taken by Nikki at two universities. And row 2 of matrix A denote the credit hours taken by Joe at two universities. Matrix B will be a column vector with cost per credit hour.
Therefore,
Now,
Tuition fee for Nikki is
