Math Is Fun Forum

The problem is as this:

You have company A that produces blue (20 tons) and yellow (16 tons ) paint. You can also produce green paint by an analogy of 2:1 i.e. 2 tons of blue and 1 ton of yellow gives 3 tons of green paint. Company A can only produce maximum of 6 tons of green though.

You can sell each ton of paint  by 100 dollar per ton. A company B can buy from you 8 to 10 tons of paint by an analogy of 2:2:1, i.e. 2 blue 2 yellow 1 green = 10 tons.

The problem is to find the maximum profit company A can make, i.e. (max) profit=120B+120Y+120G
and this requires to find the restrictions first.

Any help would be welcome cause the 'analogies' REALLY confuse me a lot!! (I mean the 2:2:1 etc etc)
