We need different types of contractors like workers to build our houses. To create a financial model in Excel to see if we can afford construction, we need information on the types of workers, their wages, hours of work required, total job time, and potential overtime. The spreadsheet model uses formulas to calculate costs in highlighted cells, with the goal of completing an extension task using only hints if needed.
