hello, this is one question just have 3 instructions to it please help me solve it.

1. You need to determine an interest rate to use (use 30 year treasury bond plus 4 percentage points you can round up to an integer "whole number") -select an interest rate and explain why you think this number should be used. Use it in your calculations in item 2 (immediately below). 2. Given the information below on options 1 and 2, carry out three forms of analysis: breakeven (payback period), ROI (return on investment), and NPV (net present value). 3. Make a recommendation on which way to proceed, based on the TCO (total cost of ownership) for each option Option 1: Purchase the FunSoft package: Cost $200,000 for software and $85,000 for hardware in year one; with $50,000 to customize it and a $40,000 annual licensing fee for the life of the contract. There will be an annual saving of $61,000 due to the layoff of a clerk. Option 2: Purchase the SoftComm package, which will operate on the vendor's hardware: Cost $250,000 for a five-year license, payable half up front and half during the first year of implementation. The maintenance contract, at $75,000 a year, includes all currently identified modifications to the software for the first three years. The clerk's hours will be cut by half, for a saving of $25,000 a year. In both cases (software options), sales are expected to increase from the current $1 million a year, by 10% per year each year (over each year's previous year's sales) after full implementation Assume a five-year life for the software, (note questions can also be found in Appendix 2 of Watt)
