[1] When revenue is 0 then there is max revenue; And when MR = MC then there is max profit?
[2] The exam question will specifically ask for the max revenue and max profit, right?
I have confused about when to calculate the Marginal revenue?
[3] Is it true either we are calculating max revenue or max profit (as per the question says) we have to calculate Marginal Revenue by this formula MR = a – 2bQ
[4] And MR is calculated to get the UNITS where Revenue = 0 and where MR = MC?
