Captain America, Iron Man and the Black Widow each have an offer for the next movie that they would like you to analyze for them and determine who will be getting the best deal. Captain America will receive $200,000 per year starting on his 35th birthday and ending on his 70th birthday (his last payment will be on his 70th birthday). He then will receive $400,000 every six months starting six months after the last payment of $200,000 and ending on his 89th birthday. He will also receive $16,000,000 on his 90th birthday and another $16,000,000 on his 95th birthday. Assuming each is celebrating their 30 birthday today, each will be around until the end of the investment payments, they have a 10% (semi-annual), which of them has the best offer?
