Manufacturing of a window requires 2 hours in work area #1 and 4 hours in work area #2. Profit is @8 dollars per doors and \$6 per window. Let D= the number of door to build and let W= number of windows to building. Develop production constraints for work areas #1 and #2. 1) 4d + 2w < 60; 2d + 4w > 48 2) 4d +2w <66; 2d + 2w <52 3) 4d + 2w>66; 2d + 4w <48 4) 4d +2w>66; 2d +4w >52
