Billy Brown, owner of Billy's Ice Cream On-the-Go, is investigating purchasing a new delivery van that would contain a custom-built refrigeration unit. The van would cost $99,000, have an eight-year useful life, and generate cost savings of $19,500 per year compared to the van currently being used. Also, Billy estimates the new van would result in the sale of 1,800 more litres of ice cream each year, which has a contribution margin of $2 per litre. (Ignore income taxes.) Required: 1. What would be the total annual cash inflows associated with the new van for capital budgeting purposes? Total annual cash intows 2. Calculate the IRR promised by the new van. (Hint Use Microsoft Excel to calculate the discount factor(s).) (Do not round intermediate calculations and round your final answer to one decimal place.) Internal rate of retum % 3. Assume that in addition to the cosh flows described above, the von will have a $18,000 salvage value at the end of eight years, Calculate the IRR. (Hint Use Microsoft Excel to calculate the discount foctor(s)) (Do not round intermediate calculations and round your final answer to one decimal place.) Internal rate of rotum
