The operations manager for the Blue Moon Brewing Co. produces two beers: Lite (L) and Dark (D). Two of his resources are constrained: production time, which is limited to 8 hours (480 minutes) per day; and malt extract (one of his ingredients), of which he can get only 900 gallons each day. To produce a keg of Lite beer requires 1 minutes of time and 3 gallons of malt extract, while each keg of Dark beer needs 2 minutes of time and 1 gallons of malt extract. Profits for Lite beer are $2.00 per keg, and profits for Dark beer are $5.00 per keg. Assume L and D are the number of light and dark kegs of beer to produce respectively.
