0 0
1 6
2 12
3 18
4 24
5 30
6 36

Explanation

(a) MR = \(\frac{\bigtriangleup TR} {\bigtriangleup Q}\)
           
 MR\(_{1}\) =  \(\frac{6 – 0}{1 - 0}\) = \(\frac{6}{1}\) = 6

MR\(_{2}\) =  \(\frac{12 - 6}{2 - 1}\) =  \(\frac{6}{1}\) = 6  

MR\(_{3}\) =  \(\frac{18 - 12}{3 - 2}\) = \(\frac{6}{1}\) = 6

MR\(_{4}\) =  \(\frac{24 - 18}{4 - 3}\) = \(\frac{6}{1}\) = 6

MR\(_{5}\) = \(\frac{30 - 24}{5 - 4}\) = \(\frac{6}{1}\) = 6

MR\(_{6}\) = \(\frac{36 -30}{6 - 5}\) = \(\frac{6}{1}\) = 6

 

(b) P = AR = \(\frac{TR}{Q}\)    e.g AR\(_{1}\) = \(\frac{6}{1}\) = $6.00

Therefore the price of a bag of maize is $6.00.

 

(c) The farmer operates in a perfectly competitive market. In perfect competition MR = AR. Since from the calculation, MR = $6.00 and AR =$6.00, then the farmer operates in perfect competition OR because price is fixed at $6.00 at all levels of output.
