Show the steps clearly

The following information was obtained for this proposal:- Two vans with refrigerated facilities will be purchased at a cost of $30,000 each. The vans have an expected life of five years and will not have a residual value at the end of their life. DDC uses straight-line depreciation. The marketing department plans to spend $100,000 on pre-launch advertising. The advertising budget for years 1 to 5 is expected to be $50,000 per annum. Van drivers: Two van drivers will be employed in years 1 and 2; three drivers will be employed in years 3, 4 and 5. Each van driver is expected to earn $25,000 per annum. . Van running costs: Costs are expected to be $10,000 in year 1 then rise by $2,000 per annum for each of the next four years. No charge will be made for delivery since a minimum order value of $30 will be set for each order. The cost of running central services - accounting, IT - will be increased by $60,000 in years 1 and 2 and by $80,000 for years 3, 4 and 5.4 No new premises are required since the direct delivery business will be run from the company's factory in Essex. The average selling price is expected to be $5 per litre. While the cost of the ingredients required to make the ice-cream will remain the same at $1.00 per litre, packaging costs will be $0.20 per litre. Factory fixed costs will not be affected by this proposal since the factory is highly automated. A consultant was employed to advise the company on this proposal and provide figures for expected demand. The consultant, who has yet to invoice the company, will be paid $21,000 for this work. Assume sufficient capacity is available at the factory to produce the ice- cream for this proposed business. The company's cost of capital is 10%. The following estimate of demand for ice-cream sales in central London was recently provided by the consultant:- Year 1- 30,000 Year 2 60,000 Year 3 80,000 Year 4 90,000 Ice-cream (litres) Year 5 100,000 Required (Total Marks 30) (a) Calculate the net present value for the proposal.
