Question:

For a construction project, a building is to be air-conditioned and 500 feet of insulated ductwork is required. The duct is made from materials costing $5.00 per foot for the steel duct and $10.00 per foot for the insulation of the duct. Engineering design will cost $1500, and labor to install the ductwork will amount to $200,000. What is the total cost of the installed ductwork for this project?
