Use the Method of Corners to Solve the Problem

Use the method of corners to solve the problem. Find the range of values that the coefficient of x can assume without changing the optimal solution.
Find the range of values that requirement 1 can assume.
Find the shadow price for requirement 1.
Identify the binding and nonbinding constraints.

A) x = 6, y = 0, C = 18 3
Constraint 1 is binding; constraint 2 is nonbinding.
B) x = 6, y = 0, C = 18 3
Both constraints are nonbinding.
C) x = 0, y = 6, C = 7
3
Both constraints are binding.
D) x = 5, y = 0, C = 18 3
Constraint 1 is binding; constraint 2 is nonbinding.
