i belive npv is 288995.09 but please do your own calculation and let me know what is correct

We are examining a new project. We expect to sell 6,300 units per year at $57 net cash flow apiece for the next 10 years. In other words, the annual operating cash flow is projected to be $576,300=$359,100. The relevant discount rate is 12 percent, and the initial investment required is $1,740,000. After the first year, the project can be dismantled and sold for $1,610,000. Suppose you think it is likely that expected sales will be revised upward to 9,300 units if the first year is a success and revised downward to 4,900 units if the first year is not a success. a. If success and failure are equally likely, what is the NPV of the project? Consider the possibility of abandonment in answering. (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) b. What is the value of the option to abandon? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) Answer is complete but not entirely correct. We are examining a new project.
