I am currently studying for finance and am unable to determine if I am using the proper formula to solve the following problems:

a sports team in an effort to solve the salary cap problem has offered a player a contract of $1 million dollars a year for the next season with the payments growing at 7% per year for the next 25 years, the player believes the best discount rate for such payments is 14% what is the value today of taking this contract?

.As an excellent student in environmental ecology you have been awarded the "Clean Effluent Prize" by state agency. You (or your estate) are to receive $300 forever from the state, or the agency will allow you to choose $400 per year over the next 25 years. The market rate of interest is 5%. What is the value of each of the two options respectively?

The potential owner/managers of the yet to be formed new In-Line Blade Company are evaluating the prospects for the business. The new equipment is expected to be $5.2 million in year 0 and have after-tax cash flows of $400,000 for the first two years, $750,000 in the next two years, and $1,200,000 per year thereafter indefinitely. The owners estimate that they require a 15% rate of return. What is the net present value of the In-Line Blade Company; should they go forward with the investment?

The BobIU Computer Graphics Co. has just produced a new multimedia graphics chipwhich will cost $5,000,000 this year to put into production. They anticipate annual net cash flows of $3 million next year and $2 million, $1 million, $.5 million, $.25 million, and then $0 over each of the following years. The two owners require a 15% return on their investment. What is the value of this investment to the firm?

The questions have multiple choice answers but I want to learn how to do the problems without having the potential answer options available. Also my professor supposedly needs to set up my financial calculator, so I also will need a tutorial on how to use it to calculate the answers for now until I can speak with him next week.

Thank You
