Please solve both questions step wise on register or answer sheet:

a. You are told that if you invest $11,100 per year for 19 years (all payments made at the beginning of each year) you will have accumulated $375,000 at the end of the period. What annual rate of return is the investment offering? b. You are valuing an investment that will pay you $27,000 per year for the first ten years, $35,000 per year for the next ten years, and $48,000 per year the following ten years (all payments are at the end of each year). If the appropriate annual discount rate is 9.00%, what is the value of the investment to you today
