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

High's Roofing performs roofing services for commercial clients. The company recently submitted a bid of $371,000 to the Shawnee School System, computed as follows: $\begin{array}{lr}\text { Construction materials } & \$ 80,000 \\\text { Labor costs } & 170,000 \\\text { Total direct costs } & \$ 250,000 \\\text { Construction overhead-30\% of labor } & 51,000 \\\text { Allocated administrative overhead } & 20,000 \\\text { Total cost } & \$ 321,000 \\\end{array}$
High 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 × 20%), producing a bid price of $371,000. Assume that 60% of construction overhead is fixed.

B. If High had no excess capacity, what would be the lowest price that the company should charge?
