Hello, I need help figuring out how my professor got these answers on our study guide. I know how he got question one, but if you could write out the equations/steps he used for questions 4-6, I would greatly appreciate it! Thank you!

& for question 5, the answer for 2c was $300,000

A 3-year project requires the acquisition of equipment that cost $2 million (including shipping and installation) and a $500,000 structure to be built on a plot of land already owned by the parent company. The plot was purchased some time ago by the company for $60,000 for use in another project that never took off and the plot has been lying idle since then. The current appraised value of the plot is $120,000. If the project takes off, it will require an initial investment of $150,000 in NWC. The project manager has received a guarantee from the parent company that, in three years, it will repurchase the structure (including the plot of land) at $620,000 (with no tax implication since it is an internal transaction). Assume no depreciation expense for the structure. Q1: Calculate the initial investment needed for the project: Ans. \$2.770.000 4. If the project is adopted, sales of its product are estimated at 300,000 units in year one and that is expected to grow by 6% per year for the following two years. The price per unit is expected to be $10 /unit in year one, increasing by 4% per year for the following two years (round P3 to two decimals). Calculate the dollar revenues for each of the next three years. Ans: $$3,000,000 in year one, $$3,307,200 in year two, and $$3,647,205.60 in year three. 5. The variable cost is expected to be $6 per unit for each of the following three years. The fixed costs are expected to be $680,000 in each of the three years. Calculate the EBIT of the project in years one through three using the answer for Q2(c) for depreciation expense. Ans: $220,000 in year one, $419,200 in year two, and $644,725.60 in year three. 6. The net working capital is expected to increase from the initial $150,000 given in Q1 above to $190,000 in year one, then decrease to $110,000 in year two (before it is fully recovered in year three). Calculate the increases in NWC in years one, two and three. Ans. $40,000 in year one, $80,000 in year two, and $110,000 in year three
