feasible region question, help please. last one

[Navyguy]

The feasible region of a maximization problem shown is determined by
12x+5y<=180
5x+4y<=98
x^3 0,y=>0

which of the following objective functions has its maximum value at (0,24.5)?
My answer is z=32x+16y is this right, from a list of possible answers.

a.z=26x+20y
b.z=32x+16y
d.z=20x+25y
d.z=24x+8y

Almost the same thing as the other one, except this time you are looking for a slope LESS steep than -5/4?

thanks.

thank you for looking at both of these problems for me, I'll try what ou said to do and see what I come up with.
