Beerco manufactures ale and beer from corn, hops, and malt. Currently, 40 lb of corn, 30 lb of hops, and 40 lb of malt are available. A barrel of ale sells for \$40 and requires 1 lb of corn, 1 lb of hops, and 2 lb of malt. A barrel of beer sells for \$50 and requires 2 lb of corn, 1 lb of hops, and 1 lb of malt. Beerco can sell all ale and beer that is produced. Assume that Beerco's goal is to maximize total sales revenue and solve the following LP:

max z = 40ALE + 50BEER
s.t. ALE + 2BEER <= 40 (Corn constraint)
ALE + BEER <= 30 (Hops constraint)
2ALE + BEER <= 40 (Malt constraint)
ALE, BEER >= 0
ALE = barrels of ale produced and BEER = barrels of beer produced.
