how do I calculate the net present value in this problem?

Pathways Appliance Company is planning to introduce a built-in blender to its line of small home appliances. Annual sales of the blender are estimated at 12,000 units at a price of $35 per unit. Variable manufacturing costs are estimated at $15 per unit, incremental fixed manufacturing costs (other than depreciation) at $60,000 annually, and incremental selling and general expenses relating to the blenders at $50,000 annually change the design of the blender every four years, this equipment will have a four-year service life with no salvage value. Depreciation will be computed on a straight-line basis. All revenue and expenses other than depreciation will be received or paid in cash. The company's combined state and federal tax rate is 40 percent. Required: a. Prepare a schedule showing the estimated annual net income from the proposal to manufacture and sell the blenders. b. Compute the annual net cash flows expected from the proposal. c. Compute the following. Assume discounted at an annual rate of 15 percent. Use Exhibits 26-3 and 26-4 where necessary Complete this question by entering your answers in the tabs below. Required A Required B Required C Compute the following. Assume discounted at an annual rate of 15 percent. Use Exhibits 26-3 and 26-4 where necessary. (Round your "PV factors" to 3 decimal places, payback period to the nearest tenth of a year and the return on average investment to the nearest tenth of a percent.)

To build the blenders, the company must invest $240,000 in molds patterns and special equipment Since the company expects to change the design of the blender every four years, this equipment will have a four-year service life with no salvage value.
