I keep having my task rejected because it says I am not showing work. I don't understand what kind of work they want me to show and because we use TaskStream to submit my paper, There isn't anyone to ask either. This is what they say:

Comments on this criterion: No revision is provided to show the work.

The optimum combination (4.5, 3) is determined but the work shown is not sufficient. Please show the work done to determine the candidate points.

This is the task and what I submitted:

C. Determine how many caseseachof Brand X and of Brand Y you recommend should be produced duringeachproduction period for optimum production if Company A wants to generate the greatest amount of profit, showing all of your work.

C.

The vertices are:

P(0, 0) = $0 + $0 = $0 profit

P(0, 6) = $0 + $180 = $180 profit

P(2.5, 5) = $100 + $150 = $250 profit

P(4.5, 3) = $180 + $90 = $270 profit

P(6, 0) = $240 + $0 = $240 profit

P = ($40*4.5) + ($30*3) = $270

I would reccomend that during optimum production, the company produce 4.5 cases of brand X and 3 cases of brand Y.

Any help is greatly appreciated.
