Answer:

We are going to set a few rules for this one:

c = the cost of placing a book bag order. (Variable already set).

b = the number of book bags purchased, and the set number of book bags purchased will be 50. (Just an example).

Now that that's set, Let's solve!

Company A:

c = 12b [substitue in values]

c = 12(50) [solve]

c = 600

So the cost of the book bags for Company A is $600.

Company B:

c = 8.25b + 55 [substitute in values]

c = 8.25(50) + 55 [solve]

c = 412 + 55 [solve]

c = 467.50

So the cost of the book bags for Company B is $467.50.

Company C:

c = 8b + 100 [substitute in values]

c = 8(50) + 100 [solve]

c = 400 + 100 [solve]

c = 500

So the cost of the book bags for Company C is $500.

Company D:

c = 15b - 55 [substitute in values]

c = 15(50) - 55 [solve]

c = 750 - 55 [solve]

c = 695

So the cost of the book bags for Company D is $695.

The least expensive company was Company B, and the most expensive company was Company D. (Not that you were asking).

I hope this helps!
