Answer:
Explanation:
2,100 square foot house consists of 400 pounds copper which costs $3.5 per pound:
Cost of copper in 2,300 square foot house = $3.5 * 400 (2300/2100) = $1533.33
Cost of copper 11 years from now = $1533.33 * (1+0.084)^11 = $3723.55
To minimize building costs, do you think that another less-expensive material (e.g., aluminum) will be substituted for copper in the electrical wiring in new homes?
Yes, it can be substituted for another less expensive material with a proper factor of safety. However, heat loss or power loss is in aluminum is higher (electrical conductivity of copper is greater). Also, maintenance cost of aliminum wire is higher.
