4. An investor is considering three types of investments: a high-risk venture into oil leases with a
potential return of 15%, a medium-risk investment in bonds with a 9% return, and a relatively safe
stock investment with a 5% return. He has $50,000 to invest. Because of the risk, he will limit his
investment in oil leases and bonds to 30% (of the $50,000) and his investment in oil leases and stock
to 50%. How much should he invest in each to maximize his return, assuming investment returns are
as expected?

- Chapter 6. Crypt-Me-Not Investments, Inc. is a new investment firm that deals exclusively with cryptocurrency investments. An investor wants to invest $75,000 in cryptocurrency next year and approaches them about investing in Solana (SOL) and Dogecoin (DOGE) which are currently selling at $175 and $1.00, respectively. The expected annual return on each unit of SOL is $180 and on each unit of DOGE is $100 and like everyone else, the investor wants to maximize their returns. The risk index associated with each unit of SOL is 1.6 and with each unit of DOGE is 1.8. Crypt-Me-Not recommends not crossing a total risk value of 2500 with the client’s investments. Moreover, since DOGE is substantially cheaper and less risky than SOL, the investor insists that a minimum of 1,000 units of DOGE in the portfolio is necessary.
