4. A footwear company is considering opening a new sales outlet. The initial cost of the outlet would be $2,000,000 incurred at the outset of the project. It is expected that rents of $500,000 per annum would have to be paid monthly in advance for the first three years, increasing to $550,000 per annum after three years. The net revenue (sales minus costs except rent) from the venture is expected to be $700,000 for the first year and $800,000 for the second year Thereafter, the net revenue is expected to grow at 10% per annum on a com- pound basis so that it is $880,000 in the third year, $968,000 in the fourth year and so on. The revenue would be received continuously throughout each year. Six years after the outset of the project, the revenue and the costs stop and the project has no further value. Calculate the internal rate of return for the project using the linear interpolation of initial guesses 5% and 6%
