Worldwide Claims Processors problem

Changing the pay for a full-time claims processor from daily $64 to $54 will change the solution to point A where X1 = 28.125 and X2 = 0. (Note that his means that there would be no part-time processors.)

Changing the daily pay for a part-time processor from $42 to $36 has no effect on the number of full-time and part-time operators hired (will still be X1 = 20.1 and X2 = 10.7), although the total cost (the value of the objective function) will be reduced to $1,671.95.
