Question 3: A company named CN is transporting three types of minerals through the train tracks: copper, titanium, and iron. There are certain constraints to how many minerals it can transfer, first of all, the train cannot transfer more than 5000 tons of minerals. Also, the quantity of copper cannot exceed double of the amount of titanium. The amount of titanium will also never exceed the amount of iron. The profits generated are 35$ per ton of copper, 20$ per ton of titanium and 10$ per ton of iron. a) Determine the quantity of each type of mineral that you will need to transport in order to maximize the profits for CN. b) In this cartesian plain, illustrate the constraints showing that the train cannot transport more than 5000 tons of minerals
