You now have $10,000, and the following investment plans are available to you during the next 3 years:

• Investment A: Every dollar invested now yields 80.10 a year from now and $1.30 3 years from now.
• Investment B: Every dollar invested now yields $0.20 a year from now and $1.10 2 years from now.
• Investment C: Every dollar invested a year from now yields $1.50 3 years from now.

During each year, you can place uninvested cash in money market funds that yield 6% interest per year. However, you can invest at most $5000 in any one of plans A, B, or C. Determine how to maximize your cash on hand 3 years from now.
