Internal Rate of Return Billy Brown, owner of Billy's Ice Cream On the Go is investigating the purchase of a new $45,000 delivery truck that would contain specially designed warming racks. The new truck would have a six-year useful life. It would save $5,400 per year over the present method of delivering pizzas. In addition, it would result in the sale of 1,800 more litres of ice cream each year. The company realizes a contribution margin of $2 per litre. Required: (Ignore income taxes.) 1. What would be the total annual cash inflows associated with the new truck for capital budgeting purposes? 2. Find the internal rate of return promised by the new truck to the nearest whole percent point. 3. In addition to the data above, assume that due to the unique warming racks, the truck will have a $13,000 salvage value at the end of six years. Under these conditions, compute the internal rate of return to the nearest whole percentage point. (Hint: You may find it helpful to use the net present value approach; find the discount rate that will cause the net present value to be closest to zero
