A constrained extremum problem with restriction $x+4y=8$ has as solution $z(1,2)=12$. The shadow price is $\lambda=-3$. Approximate the value of the minimum if we change the restriction into $x+4y=7$.

Correct: The shadow price is negative. Hence, if the constant in the constraint is lowered, then the value of the minimum increases: $12-(-3)=15$.

Go on.

Wrong: The shadow price is negative.

Try again.

Wrong: The shadow price indicates by much the value of the minimum changes approximately if the constant in the restriction increases by one.
