Question 511178: Please Help me! I don't know where to begin. I would really appreciate your help.
A city manager is deciding where to buy water. The city needs at least 10 million gallons/day and can get it either from it's own reservoir or from a pipeline in a neighboring town.The reservoir can supply up to 5 million gallons/day. The pipeline can supply up to 10 million gallons/day. The neighboring town will ony agree to provide water if the city buys at least 6 million gallons/day. The water from the reservoir costs $300 per million gallons. The water from the pipeline costs $500 per million gallons. What would you advise the city manager to do? Let x represent the number of millions of gallons from the reservoir. Let Y represent the number of millions of gallons from the pipeline.
1. Write the inequalities to represent the constraints(conditions of the problem.
2. Write the expression that represents the cost to be minimized.
3. Graph the constraints and find the feasible region.
4. find the cost for each "corner point" and find the combination that minimizes the cost.
5. What would you advise the city manager to do?
Linear programming problems, even as elementary as this one, take a good deal of time and effort to set up and solve, especially given that you want the solution graphed. Write back and I'll give you a quote for the cost of my time.
