You are given a linear programming problem.

Maximize      P = 6x + 4y

subject to   2x  +  3y  ≤ 12      Resource 1
  2x  +  y  ≤ 8   Resource 2
      y  ≥ 0  
      x  ≥ 0  
(a) Use the method of corners to solve the problem.
The maximum is P =  at 
(x, y) = 
 
 
 
 
 
 
 
.
(b) Suppose P = cx + 4y. Find the range of values that the coefficient c of x can assume without changing the optimal solution.
