A company produces a product which has a standard variable production cost of $8 per unit made up as follows:

                                                               $ Per Unit

Direct material                                 $4.60 (2kg X $2.30 per kg)

Direct labour                                     $2.10 (0.7 hours x $3.00 per hour)

Variable overhead                          $1.3

Fixed manufacturing costs are treated as period costs. The following information is available for the period just ended,
