Optimal solution for this problem without using Excel
Not what you're looking for?
Can someone teach me how to formulate the Optimal solution for this problem without using Excel?
The constraints I figured out are:
Copper .2x1 + .3x2 >= 8
Zinc .2x + .25x2 >= 6
Magnesium .15x1 + .1x2 >= 5
What is the next step?
Blacktop Refining extracts minerals from ore mined at two different sites in Montana.
Each ton of ore type 1 contains 20% copper, 20% zinc and 15% magnesium.
Each ton of ore type 2 contains 30% copper, 25% zinc and 10% magnesium.
Ore type 1 cost $90 per ton.
Ore type 2 cost $120 per ton.
Blacktop would like to buy enough ore to extract at least 8 tons of copper, 6 tons of zinc, and 5 tons of magnesium in the least costly manner
