The bakery shop is considering expanding its operations. The expansion will require new equipment costing $20,000 that would be depreciated on a straight line basis to a zero balance over the four year life of the project. The project requires $10,000 initially for networking capital all of which will be recouped at the end of the project. The project operating cash flow is $10,000 a year. What is the internal rate of the return of this project?
