Drake Jepping just discovered a one-time use, two-way time portal in the back room of a bowling alley. He can use the portal to travel to the time: Jan 1, 1936, stay for the day, and then return to Jan 1, 2021.

Drake wants to cash in on his discovery by depositing money into a bank account while in 1936. When he returns to 2021, Drake wishes to make the following expenditures:

Purchase a mansion for 19 million dollars immediately.

Purchase a professional sports team in 2025 for an estimated cost of $45 million.

Donate $50 million to his favorite business school on Jan 1, 2051.

Maintain a luxury lifestyle, which Drake estimates will cost $2 million per year for the next 40 years. (assume that the first of these payments will occur on Jan 1, 2022)

If Drake can earn 13% percent per year (simple annual rate), how much does Drake need to deposit on Jan 1, 1936 in order to be able to pay for all of his planned future expenditures?
