For number 1a, I got 58.55210 years, but I am not sure I am typing the correct signs for cash inflow and outflow into my calculator. I also get stuck on how to find the rate of return and yield to maturity. for c, I calculated 13.74 annually, but I'm not sure if that's correct. For e I got $72, and for f, I think the interest rate should be 11.13. I would love help working through each step of this.
