Mission Roofing Performs Roofing Services for Commercial Clients Mission Adds a 20% Profit Margin to All Jobs, Computed

Mission Roofing performs roofing services for commercial clients. The company recently submitted a bid of $371,000 to the Shawnee School System, computed as follows: $\begin{array} { | l | r | } \hline \text { Construction materials } & \$ 80,000 \\\hline \text { Labour costs } & 170,000 \\\hline \text { Total direct costs } & \$ 250,000 \\\hline \text { Construction overhead } - 30 \% \text { of labour } & 51,000 \\\hline \text { Allocated administrative overhead } & 20,000 \\\hline \text { Total cost } & \$ 321,000 \\\hline\end{array}$ Mission adds a 20% profit margin to all jobs, computed on the basis of total direct cost. In Shawnee's case the profit margin amounted to $50,000 ($250,000 x 20%), producing a bid price of $371,000. Assume that 60% of construction overhead is fixed.
