Investment A: Every dollar invested now yields SO. 10 a year from now and S1.30 three years from now.

Investment B: Every dollar invested now yields $0.20 a year from now and $1.10 two years from now.

Investment C: Every dollar invested a year from now yields $1.50 three 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 three years from now.
