2.1.3 You have been tasked to approximate the cost for 200m electric cabling for the upcoming project in the next six months. In the next six months, the cost of 200m of electric cableing may optimistically reduce to R3 500 or most likely remain the same at R6000/200m. However, if demand for solar panels increases, the pessimistic cost would be R8000/200m electric cabling. NB: Show all the steps of the following calculations and round off your answer to 2 decimal places Required: Using the three-point estimation method, calculate the estimation of the 200m electric cabling in the next six months.
