Isaiah runs a bakery and has estimated his cost data in an excel spreadsheet. While looking at his spreadsheet on his phone, he accidently deleted some of the data with a few accidental swipes. His cost table is given below, with ve spaces where he is missing information identied as A, B, C, D and E. All numbers are in dollars. The marginal cost gures have been calculated based on the discrete change from one row to the next. For example, 80 is the MC calculated going from Q=10 to Q=20. Your task 3: Find all the missing data. But very importantly, clearly present the maths you are using and the denitions you are using to relate the various cost curve concepts. Your task 4: (This task is not related to your Task 3) Sketch a general average total cost curve, an average variable cost, and a marginal cost curve all on the same diagram
