An investor will invest in a project that requires an investment of $10,000 at time 0 and an additional investment of $5,000 at t = 1. The project returns $2,000 at t = 3 and $6,000 at times t = 4, t = 5, and t = 6.

(a) Find the net present value for an investor for this project at an annual effective rate of 4%.

(b) Compute the internal rate of return for this investment.

I have solved it however, I am confused about whether my answer is correct. Can you confirm that NPV is $1772.575351, and IRR is 6.68982%
