Krappy Kraft Beer Inc. has two breweries in BC, with monthly capacities and production costs as follows:

Brewery	Capacity/month	Cost per six-pack
1	10000 six-packs	$1.60
2	9500 six-packs	$1.80

The product is channeled through 4 different distributors. Bart’s Beer is so popular that all stock that can be brewed is quickly purchased by the distributors, but the distributors can only handle a certain amount of product per month. Also, each distributor is willing to pay a different amount per six-pack to Bart:

Distributor	Capacity/month	Price per six-pack
A	8500	$10.75
B	4500	$9.95
C	5500	$11.00
D	6500	$10.50

Bart’s Beer Inc. has to pay the cost of shipping to the 4 distributors. The shipping cost per six-pack from the breweries to distributors is as follows:

Brewery	A	B	C	D
1	$1.00	$1.15	$1.85	$2.00
2	$0.65	$.75	$1.50	$1.75
