5.- Tuff Wheels was preparing to begin its development project for a new product to add to its small line of children's motorized vehicles. The new product is called the Kiddy Dozer. It looks like a miniature excavator, complete with caterpillar wheels and shovel. Tuff Wheels forecast the demand and cost to develop and produce the new Kiddy Dozer. The following table contains the pertinent information for this project. Tuff Wheels also submitted the project plan shown below. It shows that a product life of three years is considered until it is necessary to create a new product. a) What are the quarterly cash flows of this project and its present value (discounted at 8% )? What is the net present value? b) If actual annual sales are $50,000 per year or $70,000 per year, how will they affect the Kiddy Dozer? c) What is the effect of changing the discount rate to 9,10 or 11%
