At the start of the year a company wants to invest excess cash in one-month, three-month and six-month CD's. The company is somewhat conservative and wants to make sure it has a safety margin of cash on hand each month. (left over from previous month/ available at the outset, plus principal and interest from CD's that have become due, minus investments made at the start of the month, must be no less than the safety margin.)
These are the safety margins:
Jan $175,000
Feb $90,000
Mar $80,000
Apr $180,000
May $150,000
June $85,000

How should it maximize total earned interest? Given that Three-month CD's can only be bought in Jan and April; six-month CD's can only be bought in January.

Initial cash available is 400,000

1-mo CD's 1.0% 1 $2,000 Jan thru June
2-mo CD's 4.0% 3 $3,000 Jan and April
3-mo CD's 9.0% 6 $5,000 Jan
