Boris Milkem owns six assets that he must sell over the next three years. He expects that the sales will generate the following revenue, in millions of $
Year 1 | Year 2 | Year 3 | |
Asset 1 | 15 | 20 | 24 |
Asset 2 | 16 | 18 | 21 |
Asset 3 | 22 | 30 | 26 |
Asset 4 | 10 | 20 | 30 |
Asset 5 | 17 | 19 | 22 |
Asset 6 | 19 | 25 | 29 |
For example, if he sells asset 3 in year 2, he receives $30 million. Each asset can be sold at most once, of course. He must sell at least $20 million of assets in year 1, $30 million in year 2, and $35 million in year 3.
How can he maximize his total revenue from the sales?
