The Frank Ernst Co. wants to add an additional production line. To do this, the company must spend $100,000 to expand its current building and purchase $1.2 million in new equipment. The building expansion has a salvage value of $80,000 and the equipment has a salvage value of $390,000. This new line is expected to produce 200,000 units with a projected sales price of $4.65 per unit and a variable cost of $2.90 a unit. Gross profit from existing products is expected to decline by $29,000 a year as a result of this addition. Fixed costs are $42,000 annually. The net working capital requirement is $36,000. The company uses straight-line depreciation over the life of the product and requires a 15% rate of return. Taxes are incurred at a rate of 34%. The life of the project is five years. What is the total cash flow in year 5?
