Concept explainers
The amount invested in each type of bond by using the inverse of the coefficient matrix.
Answer to Problem 63E
Explanation of Solution
Given information:
The average yields are
Use the inverse of the coefficient matrix of this system to find the amount invested in each type of bond.
Calculation:
The given system of equation is:
Convert the augmented matrix into the row-echelon form by gauss elimination method:
Firstly find the pivot in the first column in the first row:
Eliminate the first column and make the pivot in the second column by dividing the second row by
Eliminate the second column and make the pivot in the third column by dividing the third row by
Eliminate the third column:
Therefore, the solutions are
