Unlocking the Cheapest Way of Installing Cable

What is the cheapest cost of installing the cable?

Given the scenario of installing a cable from a house to a transformer, how can we determine the most cost-effective solution?

Answer:

The cheapest cost of installing the cable is $26,800.

To find the cheapest cost of installing the cable, we need to calculate the cost of the underground part and the cost of the overhead part separately.

Let's start with the underground part. The distance from the house to the point where the underground cable attaches to a telephone pole is 60 feet. The cost of installing the underground cable is $180 per foot. Therefore, the cost of the underground part is 60 feet multiplied by $180 per foot, which equals $10,800.

Next, let's calculate the cost of the overhead part. The distance from the point where the underground cable attaches to a telephone pole to the transformer is 200 feet. The cost of installing the overhead cable is $80 per foot. Therefore, the cost of the overhead part is 200 feet multiplied by $80 per foot, which equals $16,000.

Now, we add the cost of the underground part and the cost of the overhead part together to find the total cost of installing the cable. The total cost is $10,800 plus $16,000, which equals $26,800. Therefore, the cheapest cost of installing the cable is $26,800.

Please note that the above calculation assumes a straight line for both the underground and overhead parts. If there are any bends or deviations, the cost may vary. Also, remember to round your final answer to the nearest dollar as specified in the question.
