Perfectly competitive firms are price takers. This means that they can sell as much or as little as they want, but only at the going market price. When this happens, the market price is the same as their marginal revenue. Thus, P=MC is the same as P=MR.

It can be substituted because the industry would become purely competitive.
If the firm operates in a perfectly competitive industry, profit is maximised at the ouput level where mc=mr.
(inelastic portion is when MR = negative figure) Yes , because the optimum point is when MR equals to MC and there is no hell a way when MC is negative. Other than this, when the price is at the upper proportion of monopoly demand curve, the price is always higher and the monopoly firm will earn supernormal profit. Any answer which is reasonable will be accept.

The correct formula is E = MC².
It can be substituted because the industry would become purely competitive.
If the firm operates in a perfectly competitive industry, profit is maximised at the ouput level where mc=mr.
M = mass
It's when the MR is not equal to MC. The firm in this case is unable to produce output the equals marginal revenue to marginal cost.
Einstein developed the E = mc squared formula.
