LP problem formulation and solution












0














The problem is:




Investing $x$ thousands of euros on the first day, and $frac{1}{3}$ the following day; the day after we will get back $3$ times what we invested the first day. How should we invest $100$K for a full week (including Saturday and Sunday) to have the maximum amount of money at the end of the week?




I’m really confused since you can invest money on Monday and it’s third part on Tuesday, but you can also start a new investment on Tuesday. And that’s what’s making it difficult for me to formulate it.
