Greshak Corp. is analyzing a project to expand its production capacity by adding a new machine in one of its factories. Management has narrowed the potential machines down to two candidates. Machine "A" has an initial cost of $18,000 while the initial outlay for Machines "B" will be $52,000. Based on projections provided be the company, Machine "A" will generate net relevant cash flow of $4,800 in year one, $6,500 in years two and three, $6,000 in year four, and $3,000 in year 5. Machine "B", on the other hand, is projected to generate net relevant cash flows of $13,000 in year one, $16,500 in year two, $18,350 in year three, $16,500 in year four, and $12,000 in year five.
Assuming that the relevant cost of capital for Machines "A" is 13.50% and the relevant cost of capital for Machine "B" is 8.75%, calculate the modified internal rate of return related to Greshak's proposed investment in Machine "A".
