However, for production output in excess of 14 000 units, the unit variable cost for production labour increases by 50%. This is due to a requirement for overtime working and the extra amount is payable only on the production above 14 000 units. b) The fixed cost elements are not affected by changes in activity levels. c) The variable elements of production overhead are directly related to production volume. d) The variable element of selling and distribution overhead is directly related to sales volume. Required: a) Prepare a statement of the budget cost allowance for Quarter 3. The activity levels during Quarter 3 were as follows; Units Sales 14 500 Production 15 00
