Suppose that you have the opportunity to plant trees that later can be sold for lumber. This project requires an initial outlay of money in order to purchase and plant the seedlings. No other cash flow occurs until the trees are harvested. However, you have a choice as to when to harvest. If you harvest after 1 year, you get your return quickly; but if you wait, the trees will have additional growth and the revenue generated from the sale of the trees will be greater. Assume that the cash flow streams associated with these alternatives are:

The prevailing interest rate is \(10 \%\). When is the best time to cut the trees?
