2 please help

what part is not clear i can re send.

follows: produce in order to maximize profit? The linear programming model for the problem is as follows: Max63E+955+1350s.t.1E+15+10260Fanmotors1E+25+40360CoolingcoilsBE+125+1402,500ManufacturingtimeE,S,00 The compuber solution is shown below.

Explain. Yes, the dual value will change because 25 is greater than the allowable increase of 12 . Yes, the dual value will change because 25 is greater than the allowable increase of 5 . No, the dual value will not change because there is no upper limit to how much the constraint can increase. No, the dual value will not change because 25 is less than the allowable increase of 265 . the coming production period, the company has 260 fan motors, 360 cooling coils, and 2,500 hours duce in order to maximize profit? The linear programming model for the problem is as follows
