Multiple Choice

Cox Engineering performs cement core tests in its laboratory. The following standards have been set for each core test performed: $\begin{array}{lcc}&\text { standard Hours or Quantity} &\text {standard price or Rate }\\\text { Direct materials } & 3.0 \text { pounds } & £ 0.75 \text { per pound } \\\text { Direct labour } & 0.4 \text { hours } & £ 12.00 \text { per hour } \\\text { Variable manufacturing overhead } &0.4 \text { hours } & £ 9.00 \text { per hour }\end{array}$

During March, the laboratory performed 2,000 core tests. On March 1 no direct materials (sand) were on hand. Variable manufacturing overhead is assigned to core tests on the basis of direct labour hours. The following events occurred during March:
