Document Summary
Analyzing simultaneous changes using the 100% rule: simultaneous changes in constraint rhs values. The bakery wants to evaluate the impact of (1) reducing the number of available pounds of flour to. 65 and (2) adding an additional 10 pounds of sugar. The bakery reduces flour by 15 units; allowable decrease is 24. The bakery increases sugar by 10 units; allowable increase is 30. Applying the 100% rule we see that the sum of the ratios is given by: changes. Since this satisfies the 100% rule we conclude that both changes are valid. Hence, the first change decreases the of value by 15 sh. 83 = . 45, while the second change increases the of value by. Therefore the net gain in profit is sh. 85: simultaneous changes in of coefficients. The bakery learns that a new process will increase the profit for each pie by 20% while simultaneously the profit for each cake will decrease to . 50.
