Rollo Company has developed cost formulas for the drivers of the following production activities:
$$\begin{array} { l l c c } \text { Driver } & \text { Activits } & \text { Fixed } & \text { Variale } \\\hline \text { Labour hours } & \text { Materials } & \$ 0 & \$ 20 \\\text { Labour hours } & \text { Labour } & 0 & 10 \\\text { Machine hours } & \text { Maintenance } & 10,000 & 8 \\\text { Machine hours } & \text { Machiring } & 50,000 & 2 \\\text { Number of setups } & \text { Inspections } & 30,000 & 200 \\\text { Number of setups } & \text { Setups } & 0 & 300 \\\text { Number of purchase arders } & \text { Purchasing } & 75,00 & 3\end{array}$$
-Refer to the figure.If the actual activity was 20 setups and the actual fixed cost for inspections was $28,000 and the variable cost for inspections was $5,000,what is the total variance for inspections due to?

A) favourable variance on fixed costs
B) unfavourable variance on fixed costs
C) favourable variance on variable costs
D) unfavourable variance on variable costs
