It is your birthday and you are turning 25 years old and plan to retire at age 70. You would like to receive $200,000 per month at the beginning of each month during retirement, and you plan to be retired until age 85. You also would like to buy a sweet yacht on your birthday at age 55 costing $150,000. If you have $60 today to start your investment account, and you can earn 15% APR compounded monthly, how much do you need to deposit at the end of each month until your retirement age to reach all of your financial goals?

Im using a TI-83 calculator and need to know the various inputs to use such as N, I, PV, PMT, and FV for each stage of the problem.
