help me to answer all the questions please. thank you so much.

Take the following demand and cost functions for a single plant operation: TR =$860Q $0.0402 MR = 860 0.08Q TC = $80,000 + $200 + $0.0202 MC = 20 + 0.04-Q Minimum AC = 80,000Q"2 + 0.02 = 0 a) Calculate the prot maximising level of output and price for one plant as well as the level of prot (show workings). (3 marks) b) Find the prot maximising level of output if the business were to switch to a multiplant operation taking advantage of minimum average cost. How many plants would this multi- plant operation involve? Show all workings. (6 marks) c) Find the level of prot for the multi-plant operation (show workings). (2 marks) d) Should this operation operate as a multiplant operation or a single plant operation (why or why not?) (1 mark)
