Dan Boyd is a financial planner trying to determine how to invest $100,000 for one of his clients. The cash flows for the five investments under consideration are summarized in the following table:

For example, if Dan invests $1 in investment A at the beginning of year 1, he will receive $0.45 at the beginning of year 2 and another $1.05 at the beginning of year 3. Alternatively, he can invest $1 in investment B at the beginning of year 2 and receive $1.30 at the beginning of year 4. Entries of “0.00” in the preceding table indicate times when no cash in-flows or out-flows can occur. The minimum required investment for each of the possible investments is $50,000. Also, at the beginning of each year, Dan may also place any or all of the available money in a money market account that is expected to yield 5% per year. How should Dan plan his investments if he wants to maximize the amount of money available to his client at the end of year 4?
