Carry on with the problem.. To find maximum profit, not revenue, would I take the derivative of the profit function, which I have as Profit=125*(12L+29L^2-1.1^3)-7000L. If I take the derivative of this(which I'm not sure I did right) my L=16.78 or .79. If I plug it back in...

1. So this is the answer I got 12L+29L^2-1.1L^3=0 L(12+29L-1.1L^2)=0 L=0, 26.77, -0.41 The minimum number of laborers would be 0. The maximum number of laborers would be 26.77. THe range would then be (0,26.77) because when I substitute a number >26.77 into the above equati...
