The minimum value of z=4x+10y subject to

3x+y<=to24

6x+4y<=to66

x>=to0,y>=to 0. is.

My answer after looking at a list of possible answers is 32, is this right.

a.165

b.110

c.44

d.32

Thanks for any help given.

Soroban, I just ran this through the Linear Programming solver in Maple and it gave me (0,0) as the minimum. I looked right past the origin.

Looks like the list of answers is omitting the correct minimum. That's why you're the man and I'm just a dogface .

Good 'ketch' .

**kwtolley***minimum*value is 0, not on the list. So there is a typo. From this linear programming solver, which you can use to both solve the problem or check your work, the*maximum*value is 165, answer a.

If you have linear programming problems to solve in the future, you may want to bookmark that solver.
