Henrie's Drapery Service is investigating the purchase of a new machine for cleaning and blocking drapes. The machine would cost $137,323.24, including freight and installation. Henrie's has estimated that the new machine would increase the company's cash inflows, net of expenses, by $40,000 per year. The machine would have a five-year useful life and no salvage value. Required: 1a. Compute the machine's net present value. Use a discount rate of 12%. (Any cash outflows should be indicated by a minus sign. Use Microsoft Excel to calculate present values. Do not round intermediate calculations.)

Compute the machine's internal rate of return.(Use Microsoft Excel to calculate internal rate of return. Round your percentage to two decimal places.) Internal Rate of Return: 3. Suppose that the new machine would increase the company's annual cash inflows, net of expenses, by only $37,150 per year, instead of $40,000. Under these conditions, calculate the internal rate of return.(Use Microsoft Excel to calculate internal rate of return. Round your percentage to two decimal places.) Internal Rate of Return
