Question 175018: Can you please help me with the constraints on this linear programming question?
Trenton, Michigan, a small community, is trying to establish a public transportation system of large and small vans. It can spend no more than $100,000 for both sizes of vehicles and no more than $500 per month for maintenance. The community can purchase a small van for $10,000 and maintain it for $100 a month. The large vans cost $20,000 each and can be maintained for $75 per month. Each large van carries a maximum of 15 passengers, and each small van carries a maximum of 7 passengers.

Question 176608: graph each system of constraints. find all vertices. evaluate the objective function at each vertex to find teh maximum or minimum value..:)
*** all the < and > have lines under neath them.. so all the arrows are equal or greater than...
1)x<3
y<7
x>0,y>0
maximum for p=2x+3y
2) 2x+y<30
x+y<20
x>0, y>0
minimum for c=x+4y
