Office salaries                                                        TC = 200,000 + 2x
Fuel cost                                                                 TC = 45,000 + 6x
Transport wages                                                   TC = 62,000 + 8x
Sundry costs                                                          TC = 29,965 + x

Where; TC represents the total cost per quarter
x represents the number of units produced per quarter
