Based on Robichek et al. (1965). At the beginning of month 1, Finco has $35,000 in cash. At the beginning of months 1, 2, 3, and 4, Finco receives certain revenues, after which it pays bills. (See the file P04_124.xlsx.) Any money left over can be invested for one month at the interest rate of 0.25% per month; for two months at 0.28% per month; for three months at 0.33% per month; or for four months at 0.37% per month. Determine an investment strategy that maximizes cash on hand at the beginning of month 5. If needed, round your answers to whole numbers and if your answer is zero, enter "0".
