homework assignment

Exercise five, Application of matrices
Parsonsc and I, worked together on our assignment, and are posting question number 1.
There were four parts to this question.

a) Creating a matrix that displayed the weights, (which were given to us.)
A= [5 6]

b) Writing the table as a matrix (which was also given)
B= [5 7]
[3 9]

c) Finding the total vitamin content of the cheese and meat, we multiplied matrix A by matrix B, and got our answer.
C= [A]*[B]
C=[43 89]

d) Determining the cost of the total purchase. We did this by multiplying the amount of cheese by it's price per kilogram, and the meat by it's price per kilogram.
cheese= 5kg * $2.25= $11.25
meat= 6kg * $3.50= $21.00
The total purchase costs $32.25.
