I make model spaceships. Two kinds, the Ragnarok and the Sicarious. My Ragnarok takes 5 minutes to mold, 3 for the machining and 5 for the assembly. Each Sicarious takes 6 minutes for molding, 2 minutes to machine and 18 minutes of assembly. I can only afford to run my factory to accompany for 240 minutes of molding, 120 minutes of machining and 540 minutes of assembly time. I sell the Ragnarok for 45 dollars and the Sicarious for 20 dollars. How many of each should I produce to maximize profit? What is my profit?

Let x be the number of Ragnarok and y the number of Sicarious

Here are the constraints :

5x + 6y ≤ 240

3x + 2y ≤ 120

5x + 18y ≤ 540

And we want to maximize this

45x + 20y

Look at the graph , here :

The profit will be maximized at an integer corner point in the feasible region....there is only one at (18 , 25)

So......we should produce 18 of the Ragnarok model and 25 of the Sicarious model

And the max profit is $ 1310
