Question 1207305: Suppose a building contractor has accepted orders for five ranch style
houses, seven cape cod-style houses and twelve colonial-style houses.
These orders can be represented by the rowmatrix
Q = [5712]
Furthermore, suppose the raw materials that go into each type of house
are steel, wood, glass, paint, and labour. The entries in the matrix R below
give the number of units of each raw material going into each type of
house:
a)Compute the product, QR, the amount of each raw material
needed for the contract.
b)Suppose that steel costs N15/unit, wood costs N8/unit, glass, paint
and labour cost N5, N1, and N10 per unit respectively. These costs
are represented in the column matrix:
15
8
C = 5
10
Compute the product RC, that is, the cost of each type of house.

You can put this solution on YOUR website!
Please notice that even though you wrote the words:

"The entries in the matrix R below...",
that there is no matrix R given anywhere.

Please repost, giving us matrix R, and we will try to help you.
