Dafoe, The Lone Entrepreneur is a very ambitious man.
He wants to make $1000 in the shortest amount of time!
He starts out with $0 but is currently receiving $5 per day and he can purchase the following shops at any given time:
1-Shack. Cost: $10 Income: $5/day
2-Mall. Cost $25 Income $15/day
3-Shopping Center. Cost $150 Income $150/day
The money is always paid in at night and Dafoe can purchase as many new shops as his money allows in the mornings.
What would be the best sequence of shops to be purchased to to have a balance of $1000 on hand?
How many days would that take?
Money spent comes out of his balance and so is no longer part of the needed total balance of $1000.
(In reply to re(2): Where I'm at
Aha! I had my Excel sheet set up wrong, and wasn't considering the income from the new purchases until the day after instead of the same day. Now, I'm getting 980 as well. (Funny, I thought I'd already noticed and fixed that problem. It was late, though.)
