Building Spreadsheet Models Practice The economic principles of supply and demand are important for determining the market price for a particular product. The price for the product can also be used to determine the quantity of the product supplied and demanded in the market. Create a spreadsheet model to calculate the quantity demanded and quantity supplied for a product. Assume that your company is a monopolist (the only company that supplies that particular product in the market, therefore the only company that will sell the product in the market). Fill in your model to determine the profits earned by selling that product given your calculations of quantity supplied and quantity demanded. Complete the tasks to finish the model and perform some basic analyses of profitability for different prices. Where possible, use cell references rather than coding specific values into your formulas. Enter the following inputs for your model: Demand Intercept = 600 Demand Slope = 3.5 Supply Intercept = 0 Supply Slope = 4.5 Price =$30 Fixed Costs =15000 Variable Costs = 25.
