Can somebody help me out with constraints? i have no idea how to do them and i have a word problem on them due tommorow. Willing to give a 3m rsgp reward to the first person to solve this if solved tonight before 11 PM EST, i need this ASAP.
A gold processor has two sources of gold ore, source A and source B. In order to keep his plant running, at least three tons of ore must be processed each day. Ore from source A costs $20 per ton to process, and ore from source B costs $10 per ton to process. Costs must be kep to less than $80 per day. Moreover, Federal Regulations require that the amount of ore from source B cannot exceed twice the amount of ore from source A. If ore from source A yields 2 oz. of gold per ton, and ore from source B yields 3 oz. of gold per ton, how many tons of ore from both sources must be processed each day to maximize the amount of gold extracted?
This is what i have so far, i am not sure if its right. I have to graph this and i am not quite sure what to do after this step even if i did get this right (which i probably didint)
A+B>3
20A+10B<80
A>2B
