Answer:
$1,227,250
Explanation:
Calculation for the total cost of the installed ductwork for this project
First step is to calculate the costs that have to be estimated based on unit technique for both material and insulation
Material: 7,500ft*15 lb/ft*$8.5/lb=$956,250
Insulation: 7,500ft *$10/ft=$75,000
The next step is to calculate for the Total cost
Engineering design cost $16,000,
Labor $180,000
Material $956,250
Insulation $75,000
Total cost $1,227,250
Therefore the Total cost of the installed ductwork for this project will be $1,227,250
