The first matrix represents inventory (how many

there are) of four types of objects. The second matrix

is a price matrix. The third matrix is the product of

the first two matrices.

[A1 A2] [P1] = [R1]
[B1 B2] [P2] = [R2]

Give an example of real inventory

and real prices for which the

product matrix makes sense.

Describe where you found your prices.

Complete the matrices using your values and explain

the meaning of the product.
