Kane Manufacturing has a division that produces two models of hibachis, model A and model B. To produce each modelA hibachi requires 3 lb of cast iron and 6 min of labor. To produce each modelB hibachi requires 4 lb of cast iron and 3 min of labor. The profit for each modelA hibachi is $2, and the profit for each modelB hibachi is $1.50. There are 1000 lb of cast iron and 19 laborhours available for the production of hibachis each day.
How many hibachis of each model should the division produce to maximize Kane's profit?
model A ___ hibachis
model B ___ hibachis
What is the largest profit the company can realize?

Now this is a linear programming problem (not the same chapter as the other ones you asked)
make a of A and b of B
constraints
3a+4b </= 1000 pounds iron
6a+3b </= 19*60 or 1140 minutes labor
graph those (a on x and b on y)
line 1 (iron)
(333,0) and (0,250) solution on or below)
line 2 (labor)
(190,0) and (0,380) (solution on or below)
intersection at (104,172)
so test 3 points
(0,250)
(104,172)
(190,0)
with profit = 2 x+1.5 y
point 1
p = 2(0) + 1.5*250 = $375
point 2
p = 2(104)+1.5(172) = $ 466 winner
point 3
p = 2(190) +1.5(0) = $380
point 1 p =
