How would I fill out this excel sheet? Please Please Please help me

San Mateo Technology Development, Inc. is attempting to analyze the economics of a new product and have taken a target costing approach. The product has a 25 year projected life cycle. The excel worksheet indicates the units produced and the selling price forthe entire lifecycle. Additionally, various variable and fixed costs have been indicated. The variable costs are stated on a per unit basis. The fixed costs are the entire lifecycle costs-they are not annual costs. Show the calculations and amounts necessary to determine the target manufacturing cost and cost per unit. Extend all variable and fixed cost (each line)to the total column. The second part of the problem indicates that the first five years will be dominated with additional costs necessary to reach optimum levels of production and "fine-tune" standard cost realization. Calculate what these costs represent, and indicate the target cost per unit over the remaining lifecycle years. Each year has total cost per unit identified in the per unit R&D column
