Hi I need help answer the following question

What is the amount of initial investment for the following project? The project requires buying a piece of new equipment costing $300,000, which will be depreciated straight-line to zero over 3 years. At the end of the third year of operation, the equipment will be sold for $100.000. The new project will generate $500,000 in annual sales and incur $200,000 in annual cost excluding depreciation for each of the next three years. The project also requires an immediate investment in net working capital of $100,000, which will be fully recovered at the end of three years. The average tax rate for the company is 40%.
