Find the maximum and minimum values of z=3x+2y subject to the following constraints: x ≥ 0 y ≥ 0
x+2y ≤ 4
x-y ≤ 11

There is no graph ?

D. i think it is the savings

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
