Homework Statement
Two grades of paper,grade A and grade B,are produced by a paper mill.It takes 12 minutes and 24 minutes to produce a ton of these two grades of papers respectively,with corresponding profits of $20 and $50. The mill works for 160 hours in a week and has the capacity of producing 400 tonnes of grade A and 300 tonnes of grade B paper.Find the quantity of each of these grades of paper to be produced so that the profit is maximum.
Homework Equations
See below
The Attempt at a Solution
well ,we need to find the max profit
assume 'Z' as profit and the equation for Z is Z = 20A + 50B (Objective function)
where A,B are number of grade A and grade B papers
we have to maximize Z right??
i am not sure about how to put (inequality/equality) constraints.
(400x10^3)A +(300x10^3)B <=160 ??
i don't how to relate the mass(tonnes) of these papers with time(hrs/min) in the constraints
